It would be great if you could close an explorer window using a mouse gesture, like in Opera, which it's DOWN-RIGHT. That's the one thing that would make my computer life a lot better! Just my two cents :-)
Great program, really useful, keep up the good work.
But of course you can. I have such a gesture in my global list; it executes Alt+F4 and closes Explorer and most other windows. I also have one for Ctrl+F4 which closes MDI windows within an application.
