I've been using Cap for editing and ran into several editor limitations. Filing them together since they're all related to timeline/track workflow. Happy to split into separate issues if maintainers prefer.

1. Show waveform for audio/music clips, not just video clips

Video clips on the timeline render a waveform, but standalone audio clips (music track / imported audio) either don't show a waveform or it's inconsistent. This makes it hard to align cuts to beats or spoken words without scrubbing back and forth.

Expected: Every audio-bearing clip (video's audio channel, music tracks, imported audio) should render the same kind of waveform as video clips do.

2. Multi-select clips, audio segments, or entire tracks for bulk delete/move

Currently each clip, audio segment, or track item requires individual selection and individual actions. There's no way to shift-click or drag-select multiple clips (or a whole track) and then delete or move them together.

Expected: Support marquee/shift-click multi-select across clips, audio pieces, and tracks, with bulk delete and bulk drag-to-move (keeping relative offsets between selected items).

3. Support empty/blank timeline segments (gaps) not tied to a clip, like DaVinci Resolve

Right now the overall timeline length seems to be driven entirely by the last clip's end — there's no way to insert a blank/black gap after the last clip. For example, I want the video to end but keep an audio track playing for several extra seconds over a black screen, without needing a filler video clip.
