I would like to quickly position the mouse cursor and playback the session from wherever I am pointing. I believe this is a extremely quick and easy way to be able to play from wherever I like. Reaper (play from mouse cursor position) and Studio One (locate mouse cursor) have this function and I use it all the time.
Have a feature in the Memory location window to put a clip separation everywhere there is a memory location marker for a highlighted track.
For those of us who edit LOTS of voiceovers, I will make separations at all the memory locations (bad parts in the script) so that when I'm editing....I don't move all the audio further down stream, causing it to be off it's marker.
