Actually, I hate them. I never saw a good, user-friendly dialog window yet(based on my experience with different Linux distros and Windows).
Warning! Bad english (I try to learn, so I decide to write some posts in english).
They looks the same. Left panel with quick access to different places of your PC, and central panel with files list. But hey - what is wrong with this design? I agree, maybe this is the best solution for ‘choose file to open’ task, but theese dialogs always used from another program. And I think this is the main problem.
Different hotkeys, different look, all is different. That’s why (in my opinion) vim and emacs does not use them - it’s break user experience.
