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.
You can download the script here.
