Tmux solves a problem for me. Previously I was using a combination of Screen and dvtm (http://www.brain-dump.org/projects/dvtm/) to get the equivalent of multiple screens, each with their own splits. Screen can do splits but you can't maintain splits in one screen/tab and move to another screen with independent splits. It's hard to describe, but if you've used screen or dvtm you probably know what I mean. Tmux seems to have that built in. Awesome, thanks.
