As the author of the fork (ut0mt8) I can say that yes my fork is way ahead in term of functionalities that the sergey one. I tried to re-upstream all my changes either to sergey one or to upstream without luck.
What I tried is to backport bugfixes from sergey to my repo, but I lack time to do this regularly. Apart this my fork only add functionalities that are off by default, without breaking the other logic (I hope :) ).
