It would be fantastic if right-click would produce a menu that only has relevant commands for sketch mode when in sketch mode. There is an option at the bottom which says: "Sketch" but that only brings up some commands, Finding the Trim, extend or any other sketch only commands is cumbersome.
Side note: It would be nice if the pan and orbit functions were reversed (holding Ctrl-key) in sketch mode, I pan 99% of the time in sketch mode, rotating the model is NOT desirable most of the time.
