the ability to tie the mercury transmit on/off option to a workspace layout.
if I'm doing color I want my second monitor to playback the video out. if I'm doing general editing, I want my second monitor for tabs. right now I have to go into preferences to turn on or off mercury transmit before I activate a different workspace. would be great if workspaces were smart enough to do this for me. also in general switching workspaces is much slower then it should be. every once and a while even causes a crash.
