While I don't really miss the annoyances that go with working on Windows, one thing I do wish I had in Gnome is the ability to hold the right-mouse button down on a file and drag it to get the context menu asking if I want to move or copy the file.

I realise the default tries to be sensible (like in Windows - defaults to move if on the same volume, or copy if on different) and that it can be overridden with <ctrl> or <shift> - but i'm still used to the right-mouse drag option and keep getting frustrated when it doesn't work...
