Well that was a waste of time. Tried this for my MX 3:

- The DPI slider did nothing most of the time, but sometimes the cursor movement changed when clicking a button or switching windows.

- No matter what I chose, the scroll wheel was stuck at absolute maximum sensitivity setting scrolling about a thousand lines per ratchet click. There was also no way to disable the "smart" switch to freewheel spinning.

- For some reason, tapping the thumb wheel triggered Task View. Tapping the thumb wheel isn't even listed as an interaction so no way to change or disable this.

Love the idea of an "open" version of Logi options, but this is just terribly executed. Can't state anything about the code but the bewildering behavior and weird bugs definitely smelled like vibe slop.
