Just to get this on the record while it’s on my mind.
I’d (someday! not soon!) like a way to create an “entry” that rather than being a post or a page is simply a series of items (with some sort of separator), and then a {random-item} function in a template would pull one of the items from that file to display.
Use case/inspiration: the new “previously on” block I put on my landing page that I added by hand and only have one item of interest for right now anyway.
