RazerGenie VS org.onlyoffice.desktopeditors

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

OnlyOffice

Not familiar with OnlyOffice, but you could block all network activity for it. On Linux, the easy way to do this is using Flatpak's sandboxing. Get the app via FlatHub and use Flatseal to remove its network permission. Flatseal can also be used to remove access to files you don't want it touching.

You could try OnlyOffice it feels just like a MS Office clone and is free and open source.

Just a side note, if you ever run into compatibility issues with MS Office files, OnlyOffice specifically aims to have better compatibility.

2) OnlyOffice

For office stuff, I recommend using WPS Office and OnlyOffice. OnlyOffice has less bugs, though it has less functions and compatibility with Office. As a last resort, you can install Office 365 via CrossOver if you really need it.

You can try ONLYOFFICE from Flathub, or download the .rpm from their website.
