Helpfull, but still has some room for improvements Rated 4 out of 5 stars

Does what it says it does.

Save for the fact that it makes cmd+q close even pinned tabs (which is obviously unwanted and gives about the same annoyance as to accidentaly quitting the app!).

Btw, my suggestion for the key binding to actually quit the app is to press cmd+q twice in a certain short period of time, as in Chrome.
