I have started working on a prefs replacement. I figured that it would be a good idea to ship the mod manager and preference system together, just so if you have one, you'll have the other.
If you want to contribute though, that'd be absolutely fantastic.
Edit: honestly the reason I wanted to keep BLG as an open project is so that, together, the community could make a fix-all solution instead of having a whole bunch of separate competing mods. If everyone has the same community-made enhancement suite installed, anyone is free to come in and make the changes they want to see and have them immediately distributed, instead of waiting for competing/cross functionality.
