It is so electron/chromium that I can taste it.
When I use it I can tell there's some javascript eating CPU cycles.

I really wish yall would just make ugly but lean and mean win32 apps. I feel like my mouse software shouldn't be a "load"

All modern software seems to really insult "pro" users, and logitech is one of the biggest offenders due to how ubiquitous your hardware is. I love my MX Keys and own 2 of them, and an mx master 3 (please make one for smaller hands). We paid a lot, don't give us the freemium electron style ****. Charge more for your hardware if you need to, i just need the app to get out of the way, and not trigger me when i open task manager for unrelated reasons and see the CPU time for logitech's processes
