Hurray for totally random sketchy utilities that make or break your computing experience.
Enter TwoFingerScroll, a modded version of an old google code project that brings fairly decent two finger scrolling to windows. This thing is _WAY_ better than my x220’s built in scrolling, provided by the ultranav driver. It’s quite embarassing really. Synaptics engineers (or Lenovo engineers?) should be ashamed.
Be sure to turn off the normal two finger scrolling in the ultranav tab of the mouse control panel applet when using this program. This implementation doesn’t have coasting like the mac does, but in most other respects it feels just as good.
