Nightcrawler (and other addon frameworks)

I stumbled upon xbmcswift2 last night, got very excited, only to find that it’s fallen into disrepair in the last few years and seems to have been abandoned.

Just now, I came across “nightcrawler”, hidden away within bromix’s soundcloud addon repo: https://github.com/kodinerds/repo/tree/m…ghtcrawler

This looks similar and has a lot of the features I’d be interested in. However, I couldn’t find anything googling about it. What is its current status? Is it just something used within the soundcloud plugin or can third parties use it too?

Or are there other plugin “frameworks” that are being actively developed?
