Very cool, thanks!

In a similar vein, I've been using SteerMouse (https://plentycom.jp/en/steermouse/) in the same way for many years, for the same reasons. Logi's hardware is nice, but their software just freaking sucks the electrons out of a battery. It's awful. I refuse to run their driver aka mini-OS just to do the right thing when I click a button with my thumb.

I haven't had a Mac in about a year, but SteerMouse had been installed on all of them for well over a decade prior to that. Excellent software.
