What do you use to actually manage your stuff?

Everyone here is talking about how to get the latest and best stuff, but no one is talking about how they actually manage it 😜

So, how do YOU manage your Movies / Shows / Music / eBooks / Games?

I begin:

• Plex for Movies / Shows / Music
• Kavita for eBooks and Manga
• Romm for my Gamecollection and Roms (it supports PC games aswell)
