Be able to lock the timeline & delete a V1 clip without the following V1 clips moving
When you're pretty far into a project it would be nice to be able to lock the timeline on V1 so that a clip can be removed on V1 without the following clips sucking up to fill the void. The V2-V4 & A1-A3 tracks are full and are locked to the timeline so you don't want them to move with the deletion of a clip on V1 when your intent is to insert another clip in it's place and adjust it to fill the void.

It's insanely frustrating that my audio clips will move around when I'm adjusting video clips.
