I’ve always wanted something like that, very cool!
Any plans to incorporate customizable cloud saves? I’m envisioning listing files and registry keys, maybe fetch a starting point off PCGW to give users an idea of what to expect and whatnot.
Linux client support would be great too, the Steam Deck could make great use of this.
As per the documentation, pools are basically just resource groups to make permission management easier, so they aren’t really supposed to handle anything like that. Maybe look into a RAID setup of some sort or mergerfs if you just need file level pooling.
