I think this is an important lesson in general, and one that applies in other contexts:
You don't need a "cheatsheet" for most stuff. The things you do all the time will become muscle memory, and the other stuff is easy enough to look up as it's needed.
You don't need to memorize the entire class structure of your projects. The "hot paths" get the most attention, and you'll remember the most critical stuff as you work in a codebase. There's lots of code that is basically "dark matter" - we know it's there, and it's doing something, but because we rarely review/modify it, it's only important to understand its observable effects, not the precise way that it works.
Your brain is basically like an LRU cache - the stuff that you touch a lot will stay loaded, and the stuff that you rarely use will get dropped. Embrace this property.
Yeah, -p can help with that. I’m not much for “commit grooming” - as long as a branch merges to main cleanly and passes tests, I don’t care about an “ugly” commit history.
