For one, I have one issue with using Ctrl+Super+Alt as the key for opening the shortcuts overlay. I don't think users would be able to discover it as readily as now. Something like showing it for the first 5 presses and then, for following presses, showing a small overlay like "Press Alt to show list of shortcuts" would be better in my regard.
