I've been working on a Switch Library Manager because I wanted something a bit more flexible from what I found . That and I wanted something to try litedb and blazor stuff, so I couldn't think of any better than this.
the main features are:
Web based - Can be run on docker
Runs on Windows...
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
