You know what is annoying? When you select a value in the infobar, say the percentage of a width for example, and you mouse drag to select the text and you end up accidentally moving your infobar.

I think that once you set up your toolbars and customize the interface the way you want it, you should be able to save that setting and then lock it so it can't be accidentally changed. Whenever you need to reinstall, it should also be available to you as a saved workspace or something.

That way, you can create different arrangements of toolbars based on what sort of tasks you need to accomplish.
