Cool. Too bad we'll probably never see most of those features in mainline masto. Since a lot of our features overlap I'll probably need to get a test account at some point to make sure they play well together. For instance how one posts to private groups privately is one of the areas I need to look at. I've made this work seamlessly for Zap, Friendica, Hubzilla, and Gup.pe - who all have completely different group posting mechanisms; so it's not a big deal - but the devil is in the details.
