So it turns out that you can start terminals in GVIM and manage them like buffers. I needed to tweak it a bit, but it's really nice to have this without having to learn an entirely new tool like tmux.

@madewokherd The terminal support is even better in neovim.

@madewokherd I have a binding so that ctrl-w works like other vim windows, and I map double escape to leave terminal mode.
It has worked really well for me. I use it with a tab bar too, and the result is a really nice replacement for tmux or screen.
Oh, and I use dtach with it so I can resume sessions.

@madewokherd I can't remember anything specific off the top of my head. Mostly performance I think.
