Yes I can. My personal reasons are, when coding on a laptop with no secondary screen you can take advantage of transparency to see realtime updates (behind) without switching windows. Or at times to read some crazy long command from the docs and type it at the same time. I do this with VIM, though I can turn it on/off with iterm cmd-u

Thanks for making this point. It hadn't occurred to me before. I am a desktop junkie because I want to monitor things like Slack, Spotify, etc. on my secondary, and find it hard to cope on notebooks with a single screen. But, you're right, some transparency would really help.. now to figure out how to do it on OS X :-)
