Had a feature request for something I'd call "Drop a Pin / Return to Pin".
You're working a specific section of a cut and need shots you previous discarded - say at the end of the timeline. Or perhaps its a part from another sequence. You DROP A PIN at the current point of the sequence you're editing.
You scroll to the end, copy any clips you need. You hit the RETURN TO PIN shortcut and automatically return to the part of the sequence you just left. As if you teleported from one part of the sequence to another.
To expand on the idea, you could do this from one sequence to another, but that seems like a lot to ask for. And honestly you would probably have 2 or more sequences open that you could already just pull clips in form.
On some level dropping a marker could work, but then that sort of negates the OTHER markers in the timeline. Or still keeps you adding uncessary keystrokes.
I would find a feature like this to be useful for grabbing shots at the end of a sequence, or elsewhere in my cut. Instead of jumping to the end, copying, and then show full sequence, and then cursor to where I was and then zoom in to fine cut.
This is a regular issue in my workflow in the advertising world and its something that no NLE has a quick solve for. Though I do try to mitage it with more than once sequence open for quick reference of my discarded shots.
