One problem Linux continues to have is no official app support from hardware vendors, so it's good to see the community continue building for us. If you have a Razer device, check out the new release of RazerGenie.
Great that people are developing tools but personally I use OpenRGB as its broader focused than just one manufacturer. It also uses the same underlying OpenRazer drivers for Razer devices as well as supporting other other RGB devices.
RazerGenie seems a little too focused to me but maybe there are benefits of such a tool I'm missing?
