My Ctrl + Alt + A shortcut for quickly adding a task doesn't work. I have a really long list of add-ons installed, and don't have the patience for disabling each of them and trying to find which one is interfering. :(
For your next version, I guess it would be really great if you could add in your Options dialog an option for modifying the shortcut key. Something like
Shortcut for Adding Task: Ctrl (checkbox) Alt (checkbox) Shift (checkbox) Key(input box)
Which should make many people's life easier, and shouldn't be hard to implement.
