I am running an older version of linux (RHEL 5 desktop) and I've been a bit spoiled by the mac desktop I had at my previous job. There are a few niceties I really miss, but the big one is the window management provided by SizeUp. The feature I'm looking for is a keyboard shortcut to resize and move windows to sides and corners of the screen. Is there such a tool for Linux?
If you are using compiz, this can be configured pretty easily. Download the Advanced Compiz settings manager and then look for advanced window resizing.
