From Marc Moini:
Scroll Wheel+ : Smoother, more comfortable scrolling for your trackpad or mouse. Hover Scroll: Just hover the cursor near the top or bottom of a window and relax, no need to keep scrolling. Auto Scroll: Read more comfortably with automatic, hands-free scrolling. Scroll Keys: scroll from the keyboard with the same keys in all applications. Vector Scroll: popular with Windows and Firefox users, now available for all Mac apps. Other features include independent reversal of trackpad and mouse, trackpad and scroll wheel acceleration, and more.
What's new in this version:
- Fix: on Sierra 10.12.1, Grab Scroll would have no effect when dragging the mouse very slowly (Thanks, Nelson Santos!)
- Fix: on 10.11.6 and 10.12.1, Scroll Wheel+ would not respond well to single ticks of the scroll wheel (Thanks, Mike Loose, Marc Wensauer, Kenneth Gilbert!)
- Wacom is fixing an issue in drivers 6.3.16-12 and 6.3.17-5 affecting Grab Scroll, they recommend using driver 6.3.15-3 for now.
- Other fixes and improvements.
