Multi-track editor for visuals
Currently the timeline doesn't show you the start- and end- time for each visual element (props, text). Expand the single line to be a multi-track layout with one row for each visual asset. This would help the user align the start and end of each item to match the timing other items on the same page (visual, music, SFX). For example, I use the VSDC video editing tool, and it has this multi-track UI.
