A feature I'd love to have in tools is continuous playback at higher speeds. When I'm editing a podcast I want to play it back at double speed, so I can easily check for ums and aahs etc and edit on the fly and make the process quicker than real time listening. In fact, I could playback double speed and add a pitch shift plug to make the voice normal pitch, but my workflow would be significantly faster.
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.
