The closest thing I had in mind was a while ago was creating something similar to the Phone Wiki.
But it would be in the project section and broken down into categories similar to what you suggested.
Kind of a contents page for projects.
I was to ask Amal about putting it in the project intro.
I never got around to putting a draught together, because I wasn’t sure if there would be much appetite for it.
Considering the forum search function works pretty well.
