Doing my bit?

a lot of the stuff I'm seeding is old (10+ years) and I'm the only seed

Godspeed, anon.

I consistently rely on people in situations like yours, so thank you

Based. As time goes on we rely more and more on the few who keep seeding long past the 1.0 ratio to keep a show alive. The rights to a show may change hands a dozen times before it becomes available to watch legally without spending tens of dollars on a used 20 year old disc that may or may not still work

It's not how you build a ratio, but helps so much more than seeding the latest Marvel thing. Thank you.

what is this app called?

From each according to their ability. You're good.

You get a silver medal when you hit a 1.0 ratio, and a gold medal when you hit 2.0

Qbittorrent let's you dynamically rename and move stuff based to tags. Status, and other stuff. You could get really in depth with the scripting too.

I use hard linking to manage my library. It's far from ideal, because the actual files are still stored in the jumbled shit show of files that is my downloads folder. But at least it let's me browse an ordered library of file names.

Other than linking in the filesystem as Grippler said (took me a while to understand soft and hard links on linux but they're soo useful); you can create categories with a default location (e.g. /qbt/-TV, /qbt/-Films), so you only need to pick a category when adding a torrent, and "Automatic Management mode" should save it to the right folder automagically. Also if you don't like the names you can rename both items in the torrent list and/or their corresponding foldernames and filenames, I do all this from qbittorrent (probably doable with other software as well).
