Easier to keep shares online 24/7 with a dockerised we app vs a desktop application I need to be logged in to a system for it to run. Best of both worlds would be a Nicotine+ like desktop fronted app that talked to the server component, but I don't think there is such a ui app for slskd.
Sorry, just poking at ya. Having these apps in docker does have its use cases, though. I run it in docker on my NAS since that’s where all my media files are, and I like for it to always be available to other downloaders even if my desktop is off.
