• Vue 3 - coming, slower than I'd like, but we'll get there!
• Router? Maybe in v3, will need some experimentation again - in 2.x it ended up being unfeasible
• Most of the docs should be up-to-date on the ns site - the ones we have on ns-vue site should be up-to-date, though probably missing a few things.
• There hasn't been too many issues popping up, and those that have - have been fixed mostly. The rest are generally questions. If there are any speicifc issues you are referring to, let me know - I could've easily missed some...

There haven't been many commits on the repo, but that doesn't meant it's inactive - it's been pretty stable, didn't require too much fixing...
