So far so good! Been looking for something like this without BS yearly subscription fees.
Boo to Apple for not having the good grace to make this a standard option on Mac. Kudos to the devs for putting this together!!
This app is great... and the best of all, it's free.
The best experience in gerenal has the app Smooth Scroll. But paying annually isn't my favourite. Smooze has an ugly user-interface.
