It's this kind of defeatist, responsibility-shifting attitude that holds Linux back from becoming a widely used desktop platform. What's the worst case with a fork, it stagnates and remains mostly identical to the upstream?
Especially if you do not have resources for maintenance. If you had them, and spent some time and effort in the problem domain, maybe, just maybe, you could come to the same conclusions and the results as the original you forked from.
If the conclusions are that the platform cannot support cursor acceleration the proper way (i.e. the way all commercial OSes do), the premise of the library is flawed. If not, then it must be the whole OS that's flawed, because that needs to be possible on a desktop system. Linux's cursor acceleration sucks, there is no excuse for the whole UI layer of the ecosystem being as bad as it is.
i still got the patches somewhere and will post them soon. it basically let you set mouse speed scaling on a larger scale
