Style Presets

You can now create reusable style presets — named collections of CSS properties that apply as classes to any element. Changes to a preset automatically update every element that uses it. Style Presets
Style presets applied to elements inside repeating sections now correctly propagate to all rows, not just the first.

Roll Template Editor

Logic blocks (If, Roll Total, Was Crit, etc.) now display a small icon badge on the canvas showing their type. Hover the badge to see the full condition. Template Layout
Empty logic blocks now show a visible placeholder with a drop target, making them easier to find and populate.

Infrastructure

Improved error tracking and reporting for faster issue resolution.
Added a global error page for graceful handling of unexpected errors.

Saving & Undo

Fixed an issue where the editor could trigger unnecessary saves when no actual changes were made, reducing server load and preventing version history clutter.
Drag-and-drop moves, property renames, and roll template scenario edits are now properly tracked by undo/redo, so Ctrl+Z correctly reverses these actions.
Moving a component via drag-and-drop is now recorded as a single undo step instead of multiple steps.
Sheets using templates now correctly apply layout changes to the right section of the document.

Exporting

Collapsible sections now export correctly to Roll20. Previously, the collapse toggle and header structure were missing from exported sheets, making the section non-functional. Collapsible sections also now work correctly inside repeating sections.

Layout Editor

Collapsible sections now have a new internal structure for better Roll20 compatibility. Existing sheets with collapsible sections will be automatically migrated when opened — no action is needed on your part.
When creating a collapsible section, you can now specify a custom attribute name for the toggle control. This is useful when you want to reference the collapse state elsewhere or need a predictable name. If left blank, a name is derived from the section title automatically.

Exporting

Repeating sections now export with the correct Roll20 class name format. Previously, exported repeating sections could be missing the required repeating_ prefix, causing Roll20 to not recognize them as repeating sections.
The export validation step now checks your CSS for features that Roll20 does not support, such as @import, @font-face, position: fixed, and other incompatible patterns. See Validation — Unsupported CSS Features.
Translation file export now correctly picks up display text from component labels, fixing cases where translation keys were exported with empty default values.
The export dialog no longer briefly flashes old validation results when reopened.

Logic Editor

Fixed an issue where Batch Processor nodes in repeating mode did not correctly compute running totals or per-row results in exported sheets. Previously, output values could return stale data instead of the computed result from the logic graph.
Circular dependencies between nodes are now visually flagged with an error indicator on the affected node, instead of failing silently.
Connecting edges to nodes with dynamic inputs (such as Add or Multiply) now positions the connection at the correct handle location.
Clicking a button in the layout canvas now triggers logic evaluation, matching the behavior of clicking the trigger in the Logic Editor.
In Batch Processor manual mode, you can now set which attribute each output slot writes to for the selected row directly in the Results panel.

Roll Templates

Prebuilt layout components (grids, columns, etc.) now display correctly in the roll template editor, roll output previews, and exported Roll20 sheets.
Design token CSS variables are now applied in roll template previews.

Layout Editor

Fixed a crash that prevented sheets from loading when opening the editor or dropping components onto the canvas.
Fixed an issue where the Sheet Settings modal could not be interacted with after dragging it.
Undo and redo operations are now more resilient and no longer crash on complex layout changes.
Selecting components like labels now correctly shows the selection outline in the canvas.
The Property Inspector once again shows the Attribute Name field prominently at the top when a form element is selected.
Cancelling a custom component drop no longer leaves a ghost element in the layout.

Style Editor

The CSS format button now produces consistent, stable output regardless of how many times it is pressed.

Stability

Comprehensive internal restructuring for improved maintainability and performance. No user-facing behavior changes from the restructuring itself.

Bug Fixes

Fixed an issue where the rename dialog for repeating sections appeared empty, preventing sections from being renamed. The dialog now correctly shows the current section name and allows editing it.
Fixed incorrect socket positions on If / Else logic nodes.

March 29, 2026 — Multi-Case If/Else, Group Duplication, and Stability Fixes

If / Else Node Overhaul

The If / Else node has been completely redesigned as a multi-case conditional switch.

Multiple cases — Add as many condition branches as you need, not just one. Each case has its own "When" condition input and one or more "Then" value slots.
First-match evaluation — Cases are evaluated top to bottom. The first condition that is true wins.
Dynamic slots — Each case (and the Default section) supports multiple value slots. Connect to the last empty slot and a new one appears automatically. Disconnect and trailing empties collapse.
Case management — Reorder cases with up/down arrows, remove cases with the x button. All connections are automatically updated when you reorder or remove a case.
Collapse — When you have 4 or more cases, a collapse toggle hides the case details to save canvas space.
Match highlighting — The matched case is highlighted green in the editor; unmatched cases are dimmed so you can see which path your data is taking.
Inactive case filtering — Outputs from unmatched cases are automatically ignored by downstream nodes, including Batch Processors. You can safely connect outputs from multiple cases to the same Add, Multiply, or other multi-input node — only the winning case's values flow through.

Existing If / Else nodes are automatically upgraded to the new format when you open your sheet.

Repeating Section Rename

Renaming a repeating section now automatically updates everything that references it:

Layout fields — Input and button names inside the section are updated to use the new name.
Attributes — All attributes belonging to the section (templates and row data) are renamed.
Logic nodes — Batch Processor nodes referencing the old section name are updated to the new name.

Previously, renaming a section required manually fixing names across the Layout Editor, attribute list, and Logic Editor. Now it's a single rename in the Component Details dialog.

Smarter Attribute Inputs

Attribute editing throughout the Logic Editor now uses type-aware inputs that match the field type defined in your layout:

Checkboxes, radio buttons, and select dropdowns render as dropdown menus with their valid options pre-populated from the layout.
Number fields show number inputs.
Text fields show text inputs (unchanged).

This applies to Attribute nodes, Batch Processor row tables (both manual and repeating mode), and the repeating section panel.

Logic Editor

Group duplication — You can now duplicate Batch Processor, Roll Group, and Group nodes. The duplicate includes all child nodes and connections inside the group, with the label set to "(Copy)."
Better container sizing — Batch and Roll container nodes now shrink to fit their contents when you rearrange nodes inside them.
Improved row table — The repeating section row table is now scrollable with sticky column headers.

Repeating Section Fixes

Sections with fields called "name" or "type" are now correctly recognized as repeating sections.
Checkboxes and radio buttons inside repeating sections now correctly default to their unchecked value instead of being blank.
Attribute names with a stray "attr_" prefix are now cleaned up automatically when you open the sheet.
Fixed an issue where typed inputs in repeating sections could have their attribute names incorrectly double-prefixed.
Changing a repeating section value in the Logic Editor now updates the Layout Editor in real time, and vice versa.

Stability

Fixed an issue where saving could briefly cause the Logic Editor to reload from stale data.
Fixed a batch evaluation issue where internal loops could occur when a node referenced itself inside a batch group.
Template row values now sync to the Layout Editor during batch evaluation.

Documentation

Repeating Sections now have their own dedicated docs page, with coverage of the rename feature.
If / Else node docs rewritten to cover multi-case conditions, dynamic slots, case management, and inactive case filtering.
Changelog section added to the docs site (you're reading it!).
