Better cross referencing of functions.
I needed to do this: Always get the name for a specific category ID. Period. I didn't need to get the category name related to a post or anything like that. I didn't need to query categories to find a specific one. I experimented with using the various functions referenced from get_the_catgegory (single_cat_name, etc.), but I couldn't seem to find a simple functions for "give me the name of category 1".
I tried all kinds of searches for "get category name", but the results all seemed to lead back to get_the_category or one of its variations. In desperation, I "guessed" at "get_cat_name" and typed it in Google. Sure enough, there it was - but it was listed nowhere near all of the other category functions - it didn't reference them, and they didn't reference it.
I could have saved a ton of time if "get_cat_name" had been cross referenced at the "get_the_category" page.
