Earlier quoted context omitted.
Well, once you're bolting on plugins for features that come with iTerm2, why not use iTerm2?
Because I find iTerm to be a pile of crap on most of my systems
Out of curiosity iTerm or iTerm2? If the latter what is crap about it?
I have one huge gripe that I haven't been able to fix but its not that huge a deal. Every so often the terminal will lose its mind and start displaying mouse escape sequences. Nothing resets it out of this state, have to close whatever window I have open and start anew. Not a huge deal due to tmux but annoying enough to frustrate.
