1) I would like to set middle button to do "look up" or "force click" thing, but there is no such option. Funnily, there are some articles suggesting that it was possible before. https://9to5mac.com/2019/12/18/macos-how-to-set-up-force-click-with-logitech-mx-master-mouse/
2) I would like to make distance needed to activate gesture smaller.
3) Scroll feels junky, also if you spin the wheel fast and let it spin, the stop feels rather abrupt, compared to mac trackpad experience. Previously I used these software, which felt somewhat better, but still not perfect. (https://github.com/noah-nuebling/mac-mouse-fix) More scroll adjustments, like inertia, might be good. Maybe junkiness might be attributed to bluetooth (I have not tried nanoreciever yet) or hardware limitations of the wheel sensor, dunno.
