If I click on the StrokeIt tray icon, I get the Command Editor, of course. I can then choose an application, and I see its defined gestures.
And, if I select Global Actions, for example, I see that 'Q' is Quit. But, what if I don't know the 'Q' gesure? Of course, I could check the online documentation. But, in the "Gestures that will execute this action" area, it would be even better if there was an icon showing the gesture next to the 'Q'.
