I use the G305 which is even more barebones in the buttons, however I remapped the dpi button to be a sort of "omnifunctional activator" that I combine Lua scripting from LGS with other Autoit scripting for accessing WinAPI to achieve multitouch gestures with my mouse. The UX isn't quite refined enough to be a standalone application that I can share on GitHub yet, but eventually I'll figure out how to turn them into a self-contained package.

That’s dope! I’m macOS so I just use karabiner for all button remapping. Tho I recently got a QMK board and have been meaning to add some mouse actions to it (purely ergonomic reasons, ideally use my mouse less and less). That’s nice u have LGS tho it’s at least ostensibly better than the absolute trash ghuh is. Also pretty cool u can extend LGS with lua!

A little known secret on Windows is that you can still get LGS via winget:

    winget install Logitech.LGS
