Sometimes after working on a few TextMate windows, one of them will have its file directory tree drawer missing. I don’t know why this happens but to bring back the drawer, just go to the menu bar and click View -> Show Project Drawer.
Also another tip is, if you prefer the drawer to come out from the right side but it always comes out from the left, all you need to do is
1. Hide the drawer
2. Move your TextMate window to the left side of your screen so there is not much space to display the drawer on the left
3. Show the drawer
Yea, it’s that easy. Happy programming!
