Smooth scrolling for external mice?

Hi there,

Big fan of BTT and used it for years. I've recently been using an external mouse now and then (Steelseries Rival 500), and I love the fact that I can reverse the scroll wheel action with BTT (Apple wants up to be down, per the trackpad's "natural scrolling" setting, and vice versa), but it doesn't retain the "smoothness" of the trackpad's scroll.

Andreas, is there a setting that enables a "smooth scroll" feature for external mice, by chance? If not, would you ever consider putting one in? If not, I totally understand.

Thanks, and keep up the great work!
