Hi Paiousaur. Have you considered making several Ultimate distributrions, with varying amount of add-ons? From a basic one, with just some add-ons over the stock MorphOS 2.5 setup, all the way to the complete set that your pack already has. Something like "light", "regular" and "full" versions. The problem with this is that it might triple the amount of work.

The best would be a very clever install script, that allowed thew user to pick add-ons onwe by one - with careful dependency checking, of course.
