There are few things more annoying than the taskbar deciding to pop up when I'm working near the bottom of the screen. Much more annoying than having to use a key combination to bring it up when I need it.
I would love to be able to have a shortcut key that requires TWO following keys to be pressed to execute the command, e.g. [Shortcut key] +[Q+1]. This would enable a vast numberof key commands and macros to be easily mapped to the keyboard.
I would love a window where macros could be launched easily using onscreen buttons. There aren't really enough keys on a computer keyboard, and a launchpad window would be great for using macros without using (or having to remember) keyboard shortcuts.
