After using AAP for a couple of weeks, I have found that I don’t really need the GUI for other than changing the guide track.
I have therefor written a small apple-script that allows me to assign a short cut to the “render” button.
The script will open AAP if it’s not already open, and then press render.
You assign a short-cut using System Preferences/Keyboard/Shortcuts.
I’m not sure if I’m able, my programming skills are limited:) But you can email me directly and explain what you would like to achieve. I it might be that I can help.
