An absolute staple of my development setup, and one of those rare tools that always just seems to work. Thanks for all the work!

Sidebar: if you're a die-hard tmux user in Linux, and you do something like, say, open vim and then realize you haven't opened it in tmux, check out https://github.com/nelhage/reptyr - it lets you do things like ctrl-z to background vim, start tmux, then steal the vim process into your new tmux session. Pretty cool!
