"stop building" and "cancel order" are both bound to the same command. Say you have a tml launcher and queued up 3 tmls. Now you want to cancel the queue for some reason. You cannot do that without manually deleting all attack commands, because if you pressed the stop button the missile currently being build will be canceled. But often with tmls it is a matter of 1 or 2 seconds, which is not enough time to manually delete all the orders. This problem obviously exists for all units that can build something (and are not a factory) in some form. I find this to be a big flaw in the UI that has persisted since the release of the game.
Would it be possible to decouple those two and make a separate button and hotkey for them? Or do they already have separate hotkies and I just missed that?
