the keyboard k83 doesn't save the configurations in the keyboard after it has been turned off. when it is turned back on, the configurations that were made inside the iCUE aren't effective anymore. Most specifically, "Swap F-Key Functions". Very frustrating. also this should be part of the firmware saving the configs inside the keyboard itself thus eliminating the need for the iCUE to run in the background for such a mundane setting.
more often than not, K83 firmware triggers a bug where if you swipe down it also slides right, and if you swipe up it also slides left. It's in the firmware because even if you change computers the bug persists. Happens specially when the keyboard is low on battery, probably has something to do with electric voltage and package data rate being compromised.
also the k83 lights go out after 10 seconds, that's fine I understand, but there should be an option to change it to 30 60 120 180 360 seconds, 10 seconds is way too low, everytime I look at the keyboard the lights are off, so the experience is almost the same as having a keyboard that has no lights, so what's the point? this has to be tuned or at least tunable, right now the UX is terrible.
ps: there's no option to remap the k83's joystick click action
