Is it possible to enable/disable features? Since installing, my prompt has been rather buggy, and there are some features I don't particularly care for, but others I really like. For example, my python virtualenv prompt gets broken into two lines, both with a mark, which causes line lengths to misbehave too sometimes. Alternatively, not to sound like a downer, but is there a way to uninstall shell integration? Thanks!
