In KM 12, do add a `switch` over applications `at front`

[nikivi]

I really dislove that I hate to nest things like this, it's ugly. I wish I could just switch over apps that are at the front and add actions accordingly. I have macros where I have to do this deep nesting quite deep inside the if/else conditions and it would be a lot cleaner and readable if I could just switch.

You could test against the token for the front application.
