RazerGenie VS Floatplane-Downloader

well there's Razer genie if you happen to run a superior operating system like Arch linux or something...

openrazer: https://openrazer.github.io/ (also has list of supported devices) razergenie: https://github.com/z3ntu/RazerGenie

Also I tried RazerGenie and razerCommander.

If you have multi-button mouse, I recommend Piper or input-remapper. Again, I have had issues using them on Wayland, but they are otherwise pretty good softwares. There is also RazerGenie / RazerCommander if you use their stuff.

For your Razer peripherals there is a project called openrazer. For a graphical way to manage it you could install something like RazerGenie or Polychromatic

Edit: if anyone in the future finds this and is in the same boat, there is a docker container to automatically download the floatplane vids and then add it to your Plex server so you can watch it buffering free: https://github.com/Inrixia/Floatplane-Downloader

I think the confusion is with the URL's GitHub uses, for example this link https://github.com/Inrixia/Floatplane-Downloader/blob/master/package.json looks like it might be for a raw JSON file, but it's not. I expect this is basically what Linus tried to right-click and save as. If it actually was just a JSON file that would have worked.
