History Stack

The History Stack window (F6) displays a three level hierarchy of all undoable actions in collapsible speech-bubble capsules. Each event block shows a timestamp, duration, and category color. Events of the same category are automatically grouped into a parent capsule with dynamically appended children.

Three-Level Hierarchy

1. Exploration Blocks (root level)
   Each creative iteration is wrapped in an "Exploration N" block. When you undo then perform new actions, a new exploration block is automatically created, preserving old history as inactive (diagonal stripe overlay). Click the + button in the toolbar to manually create a new exploration branch. Click an exploration block's title to inline-rename it.

2. Category Groups (children of exploration blocks)
   Auto-grouped by event category (Navigation, Display Toggles, Selection, Create, etc.). Each category group composites its undo/redo across all its individual operations. Undo/redo at this level is ⌘+Z/⌘+Shift+Z within the current block (within-block undo), or jumps between entire exploration blocks (block-level undo when at block boundaries).

3. Individual Operations (children of category groups)
   Atomic events like "Zoom", "Pan", "Toggle Wireframe", "Adjust Up". Always undone/redone as part of their parent category group.

Undo/Redo Behavior

• Within-block
  ⌘+Z undoes the last category group in the current exploration block. ⌘+Shift+Z redoes the last undone category group. Each category group's children are undone/redone together.

• Block-level
  When at the first category group of a block, ⌘+Z jumps to the previous exploration block (undoing all its events). ⌘+Shift+Z from a fully-active block jumps to the next exploration block. Block-level navigation is also available via the ↩/↪ buttons on each block.

• Exploration branching
  If you undo to a previous block and perform new actions, a new "Exploration N" block is created with those actions, while the old future blocks remain visible as inactive history. You can always navigate back to them.

Save / Load

The Load and Save toolbar buttons default to the History/ subfolder under ~/Library/Application Support/com.Lightfielder.Viewport/. Saved JSONC files store the full event tree including event IDs, categories, timestamps, elapsed times, the current undo/redo position, within-block undone event IDs, and per-event fold/unfold states. Loading a file fully restores the History Stack UI to its saved state.
