I myself coined a term "kitchenware principle" that I have applied to my codebase as well. You put forks and knives adjacent because they serve similar utility and common purpose. Same with plates, cups, weird gadgets in separate drawer.

You should organize your code similarly and with as little fanfare. They are just tools, dont get clever with them. Sometimes, you get too many forks in same holder so you have to divide them but again, common sense prevails.
