Sad to see its not at least CSS customizable, I'm not a big fan of the gradient-to-picture ratio (unless that's changeable in the dashboard?).

Seems like most of these new Fandom-oriented features block out CSS/JS customization which is a shame since it makes them look way too different compared to the rest of the wiki (Disussions for example). Makes me worry if future features will ever support CSS/JS for once.
