(I have been using Shotcut for a couple of years now, and I really love the software.)
I would like to be able to (or have the system default to) neutralizing the snap to function for the start/end frames of elements that are in tracks that are muted. I frequently find that I cannot drag an element to the frame that I want because of another element 1-3 frames away. That element is never in the track(s) that I am currently working on, and it seems to me that this is the easiest way to avoid that situation.
