Bridging the Gap

From what I’ve gathered, most folks on here are several years strong in performing magic.
As some UPG on this forums have said, some grimoires may benefit from shifting to a more user-friendly format.
So, what do you all consider to be “mid range” topics for a grimoire?

I find any grimoire can be mid-range, but that’s from the idea that the practitioner has built a proper foundation.
