…rawn pills A trim whose clip is gone is stored and cleared but has no pill, so the button stayed hidden while the action still had something to clear. Refs #723.

What
A Clear timeline button in the timeline toolbar. It removes every edit region in one action.
Clears the five edit lanes, on all clips:
Deliberately keeps everything the user added as content rather than as an edit:
Behaviour:
V4Timeline.tsx, so swapping it is a one-word change.Why
Auto-zoom after recording stays on by default. Someone who does not want the zooms had to delete them one by one. Per maintainer decision it is not made an option; one click clears the edits instead.
How
clearEditRegionsindocument/timeline.tsholds one entry perRegionKindexceptaudio, as aRecord, so a new region kind fails to compile until it is decided.useTimelineexposeshasEditRegions(true while any of those regions is stored) andclearTimeline, which saves the cleared document with{ history: true }and drops the selection. The toolbar reads the samehasEditRegionsthe action guards on, so the two cannot drift apart. Keybuttons.clearTimelinein all 15 locales with real translations. One row in thedocumentWriteAudittable (a gesture).Verified
