Kinda curious if there if this is still being worked on and adding new features, cause its a handy tool, but could do with some added features.

It's still being worked on, however you should temper your expectation especially if you're not using it with models made by Mannequin Character Generator.
This tool is made for Mannequin's users first and foremost, so various features depend on it. For example, Mannequin cannot output models compatible with hand tracking at the moment, so we won't bother working on that feature in Puppetstring.
