Why can't I resize the Toolshelf? So my problem is that I cannot resize the toolshelf in any direction, which is really annoying since I don't see the tabs because there are so many of them. I'd like to resize it and I have no idea why I cannot. And it's just the toolshelf, other areas can be resized with no problem.
pressing Numpad + or Numpad - you can zoom in or out on any window (or control) in Blender.

To resize the panel drag it with the left mouse button.
