The pigeonholes

Pigeonholes, in the Tools folder on the desk, lists every open window, one slot each: what it is, whether it is folded away, pushed to one side or making a noise, and how many frames it holds. Any of them can be brought forward, folded away or closed from there. It doesn’t say how much memory a window uses, because a web page isn’t allowed to read that, and it would rather say so than guess.

The codex proposes that the workshop’s post is sorted into it, and that nobody has ever collected any. This is proposed by the codex and is not canon until approved.
