I keep a list, as json, but I also make sure that they're all listed on the NIP repo ReadMe (scroll down to Events).
https://github.com/nostr-protocol/nips/blob/master/README.md
Sorry, not quite. That’s the NIPs, which are also numbered.
Each “event” in Nostr has a numeric “kind” field. Regular text notes like these have kind=1. Reactions (likes) have kind=7, etc.
When people make Nostr-based apps, often they’ll use new, previously unclaimed kind numbers to have specific meanings for their apps.
I seem to recall someone making a registry of these kind number meanings. Maybe nostr:npub1m4ny6hjqzepn4rxknuq94c2gpqzr29ufkkw7ttcxyak7v43n6vvsajc2jl ?

Thank you! Yeah, I’m working on an app, and need to pick a kind number.
My algo is:
1. concatenate the project name and purpose as a string.
2. SHA256 hash the name-purpose
3. Take the first 4 bytes as int 32.
4. Modulo this number and add basis for specific kind range.
So for example, if you need a parameterized replaceable event, you mod 10000 and add 10000.
Has anyone already written guidance of this sort for picking kind numbers for app purposes?
