/vt/ - Virtual Youtubers

Hey guys, I downloaded A1111 a few days ago after lurking for a while and I'm getting started on this (lazily). It's fine if I ask around a little bit, right?? I swear I'm also reading the guides.
1 - I see that there are millions of models around, how do you guys keep track of that? Or do you find a good model and stick to it?
2 - Sometimes I see in the filenames here something like 01892-####### which I noticed is the number of images generated in a day (for me at least). How do you manage that many files? I use hydrus network for other stuff, would that work here too?
3 - Usually do you use many extensions to tinker with the end result or do you just do prompt magic? I wanna know what to focus on learning first
