1. I think the tiles would be more usable if it had a hotkey to bring the tiles to the top like DX widgets.
2. It'd be nice if the tiles could snap to each other. (With a little spacing between them. Possible matching the height of the moved window to the height of the window it snapped to.) Just something that would make it look cleaner and neater.
3. I'm having some issues when I click Shift+Minimize that the window gets closed instead.
