This is perhaps not so much a wish, but more of a thought I've had for many years about keyboard shortcuts:
A. It makes sense to have the most commonly used actions available to assign keyboard shortcuts to.
B. It would be nice if each and every function would be available to assign a keyboard shortcut to.
Neither A or B are ideal for every user.
Perhaps it would be possible to have the Hotkeys settings menu by default show the most common ones, but have a 'show all' button to display all possible actions?
