I use Jellyfin. You have to install the Bookshelf plugin (or at least I didn’t the time I set it up, may be a default now). Saves progress, and gives me one less service to manage as I use Jellyfin for Movies, TV, and Music libraries already.
I’m good with sticking with plain old motherfucker and have absolutely zero intention of replacing it with some convoluted bullshit alternative. I figure if he/she/it/they/them are offended by my use of the word motherfucker then it’s aimed at he/she/it/they/them anyway and all those motherfuckers can get fucked and stay fucked. Tired of catering to everyone’s sensibilities. Grow a pair, or a twat, put on your grown up panties and get the fuck over it.
That’s not what the other poster said. He said “Non Featured” servers. You have to do a DNS hack on the switch to connect to a private server.
