That's kind of what I've been doing for over 6 months now.
But I have no intension of adding commands for all kinds of scripts. Users that want to add commands for whatever scripts they use can very easy add them themself.
I will take a look at the commands for ioBanana (at some point) and then update the command set, my way. Other scripts that are really good and useful might end up in the fce too some day.
