UX Rework Design — 2026-04-03

Context

After regular use, three pain points emerged:

Autosave generates too many snapshots (moves spam the timeline bar)
Branching UI is confusing and never used
No way to know what specifically changed when hovering a snapshot

Changes

1. Autosave — Skip move-only snapshots

Problem: Moving nodes triggers auto-captures as frequently as structural changes, filling the timeline fast.

Solution: Add a guard in the capture path: if detectChangeType() returns 'move', skip the save and return early. No new config, no debounce changes.

Existing snapshots are unaffected.

2. Detailed diff metadata on hover

Problem: Snapshot icons show a change type icon but not what specifically changed.

Solution: At capture time, after detectChangeType(), run a new computeDetailedDiff(prevGraph, currentGraph) that produces:

{
  "added": ["CLIPTextEncode", "KSampler"],
  "removed": ["VAEDecode"],
  "params": ["KSampler: steps 20→30", "KSampler: cfg 7→9"]
}

This object is stored in snapshot metadata. On hover in the sidebar or timeline, a tooltip renders these lines as plain text.

For snapshots captured before this change (no diff field), the tooltip falls back to the existing change type label.

Diff computation:

Added/removed nodes: compare node sets by ID, label by title+type
Changed params: compare widgets_values per node between previous and current graph

3. Hide branching UI

Problem: Branch navigation is confusing and adds visual noise.

Solution: Add const BRANCHING_ENABLED = false at the top of snapshot_manager.js. All branch UI rendering (the < 1/2 > navigator, branch buttons, activeBranchSelections sidebar/timeline logic) checks this flag and skips when false.

Underlying data and code (parentId, buildSnapshotTree, etc.) are left intact.

Out of Scope

Removing branching code
Making branching a user-facing settings toggle
Changing debounce timing
Retroactively hiding or deleting move-type snapshots
