I did not, had no idea about it. Unfortunately the mouse started to fall apart a bit and Logitech has very few MMO mice meeting my needs, so I decided to switch to Razer Naga Pro V2. I haven’t tried configuring it on Linux yet, as I’m pretty sure the major supporting app doesn’t have V2 support yet.
I might actually contribute back based on the steps listed in the open issue for it. It just requires time, effort, and motivation I don’t have right now.
It’s also been archived for a year with no revamp in sight.
