Keyboard Shortcut Heat Map
It would be fantastic to be able to see a 'heat map' of your mouse clicks keypresses and shortcuts in After Effects so you can see what you're pressing most often. This way you could find out your most common shortcuts and possibly remap them to shortcuts. This is a longshot but I can see this helping because everyone has such unique workflows. Could also be used to gather data for Adboe to further optimize menu items/shortcuts/etc.
