Would it be possible to have a "Launch" feature added so that the program could open and run other programs specified in the scripts.

I had mistakenly thought that it could already do that after running Banjo's tutorial, and seeing my media player open and run.

I have put a longer post in Various infos / Roadmap (posted before I realised my mistake) which will show the immediate potential this offers.

It is possible, see this thread.
(as I understand, you're talking about some windows-only application ?)
