"TextMate will automatically close tabs that hasn’t been used in a while, when the tab bar overflows".

So keeping every file open is impossible anyways.

Why would you _ever_ do that? Now that we have tabs and the wonderful single-window display, I just leave everything open. Or you could minimize instead of closing.


Well, the beauty of great software is that it doesn't force everyone to use it the same way :)

Minimising wouldn't really work, I'm not trying to hide or move TM out the way.

If it works for you though, great :-)
