I want to have different GUI on the mods I'm using, but I don't really know how to mod a mod, so I'll just post a GUI suggestion:
Before:

After:

I personally believe that commands like "wait", "clear group", and the maneuver thing are obsolete. Correct me if I'm wrong, but I think you should have an option to hide them. This GUI aims for simplicity and being small and easily understandable.
Right now it uses only two lines, but obviously this can easily be stretched to three or four to fit more buttons. However that is less necessary when you have less useless buttons overall.
