Writing wishlists is fine - the whole OTW and AO3 started from a wishlist that people thought was unrealistic at first, but a surprising amount has since been achieved. Dream big!

I've coded a couple of these, which will hopefully be included in the next release, if they get approved and so on, and I'm keeping the list saved for the future to try and add more options. We've also got some bigger plans in the pipeline, which should make all of this slightly easier, but aren't confirmed or announced yet. Most of the font style and size changes you make in a skin should affect menus, buttons, etc. as well as actual works, though, so if that's not working, can you raise a support request, please?

For the gap between wordcount, chapters and so on, I've raised it for discussion, so we'll see if anything comes of it. That section of the page was one of the hardest to design - to get all the key information there about the work, while also keeping it both small and readable, is tricky. Nothing we ever do is going to please everyone on that, but there's still plenty of room for improvement, and I can definitely see what you mean about the numbers.

(Disclaimer: I'm an AD&T committee member, but this is not an official announcement.)
