I must admit I'm impressed. Barring a very slight jerkiness at some random times it actually feels native: fluid, fast, and the "physics" is very, very close. In comparison iScroll 4 is better on general smoothness but feels strangely alien to iOS (notably the inertia bounce at list ends).

With the swarm of crappy alternatives - barely mimicking the native behaviour - I saw before I was giving up on the hope that something like this could even remotely exist.
