Steam Machine and Steam Deck support will be coming to Nexus Mods' Windows-only mod manager at some point
Ah, cool. The world's foremost hosts of unofficial Skyrim additions you'd rather not have to explain to an elderly relative, Nexus Mods, have committed to bringing SteamOS support to their mod manager Vortex at some point down the line. That'll mean you can use it with the Steam Machine and Steam Deck, if you fancy a modded playthrough on the go or via a smaller package.
