A tool or function that disregards clip edges once multiple have been selected
When selecting a bunch of clips its often because the user want to relocate them on the timeline not resize/ trim any of them. Having a function (or setting to default) that rejects the ends of clips once multiple are selected will make moving many short clips far easier, instead of the regular mis-selection of a clip's end resulting in the trim tool being activated.
This could also be implemented with "keyframe bands" on clips. If multiple clips are selected these opacity bands for example could be rejected instead of accidentally grabbing and altering these parameters.
