Live Key - option to use as Touch

As a former Hog 2 specialist working in TV for the BBC, the 'Active' button was probably one of my most pressed buttons.
I really missed it on Hog 3 and never really adapted to 'Touch' being one of the little toolbar buttons below the screen. It really slowed me down and I found it very, very frustrating.

Now I've finally got on to Hog 4, I am disappointed that 'Touch' still isn't a proper key like on the 2.

As someone who never uses the Live key, I would like an option to set the Live key to be either Touch or Suck.

This would really help me a lot and speed up programming hugely.

Thank you.
