    BetterTouchTool is the best alternative to SizeUp for me because I only wanted to use SizeUp for keyboard shortcuts to move windows between desktops. SizeUp it looking to be pretty dated, and requires you to release all modifier keys in order to initiate the move to a different desktop. BetterTouchTool is a behemoth app that does 100x more than what SizeUp does, but that works for me.

    It has nothing to do with automatic window resizing and positioning
