Another easy PR idea: add page count to available sort options on the User Page.
Easy, but I don't think it really solves anything. Where possible lets focus our PRs on resolving existing issues.
\pagelines, possibly as folding labels (naturalcrit/homebrewery#1667) or even styling that applies to the whole page. But showing page contents might be enough for now until we make that change since I think it's still a way off.
cssblock for the style tab, but for metadata. Probably needs a whole separate PR just to set that up.
