It would be useful to have a keyboard shortcut for accessing the recent project list. After all, it’s the recent list. The whole reason for the list is to give users fast access to recent projects, and yet there’s no keyboard shortcut to it.
I would gladly trade other shortcuts for a recent shortcut. (May I gently suggest that allowing users to bind their own keyboard shortcuts in a Preferences panel would be the most flexible and long lived solution. That way everyone could dump the bindings they never use, and use them for Balsamiq functions that they DO use frequently.)
