Does FANDOM staff read any of this or is it just for venting?
Hah well... all their discussion info asks for feedback, so we can only hope...
One I just thought of by chance. Maybe add the option to change / cancel your vote on polls, because I accidentally misclicked on Syntax highlighting and can't seem to change my vote.
Other than that; wikitext, markdown and actual site-wide customization options (e.g. CSS).
A background like on the rest of the wiki would be nice
