Welcome back! 
For my part, the thanks are appreciated, and I’m glad if I’ve helped!
As to new people prompting new developments, funnily enough, yes.
Aside from the usual bug-fixes and suchlike, @svf recently started a thread that has become a project to create new sample-programs for the engine. You should find that here:

That in turn has lead to a project-thread aiming to create a small showcase game. This thread should be found here:

And finally, good luck with your project!
