I would like the ability to save all open files as a session. A lot of times I will have 5-10 open files and suddenly I will have to switch contexts. This usually means closing all tabs and opening a new set of files. It would be nice to save my current open tabs so that I can come back to them at a later time.
The ability to view all my sessions in a popup (ie like cmd-p) or to be able to cycle through my available sessions would be great.
