1) I'd like to be able to have an option for each group to have a sort of checkbox system like in some e-mails, with 'select all', 'select none', or individually do it for just some selected characters. In order to make them private or move them.
2) I'd love it if you could block people you don't want stalking your characters/account. And by this I mean once you block them, they can't follow you or see your characters. It'd make me feel more secure, at least.
3) More questions! I love them, but there aren't enough. XD
4) Perhaps maybe consider a color/theme option for users' basic profile pages. o3o
5) As suggested by others, linking with other friends' characters would be awesome.
6) Also! I would love it if you could add a sort of "next/previous" pair of buttons on each character page so you don't have to keep going back to the main group and selecting the next one to edit/look at.
7) Oh right! I also want that stupid "this has been updated!" popup gone. Or at least just refreshed/replaced up at the top without creating a giant list of the same popup when info is changed on a character.
