When I open a folder with textmate, either from finder, quicksilver, or the shell addon (mate), the project drawer pops up. Is there a way this can be hidden by default?
There doesn't seem to be a setting for not showing the drawer by default.
If you can live without the drawer, you can make it as small as possible:
Which will leave you with a very small (but still slightly visible) drawer (can't post images yet). That last remnant would be even less noticeable if you install Ciarán Walsh’s ProjectPlus plugin.
The neatest solution would be to take the source code of ProjectPlus, and add the desired behaviour.
