Suggestion for macro option for Synapse

I was thinking what if there was a macro option where if the key, or button the macro was set on was pressed for a certain amount of time, it would activate the set macro like a hold delay. I think this could be very useful in binding things in a way where you could essentially have two ways to press one key. For a game example, binding that macro option to your spacebar and be able to regular jump by tapping once. And then holding it down to use a jump ability (e.g. double jump or boost). I feel this would be a great option to put in and would only help more people.
