I'm not sure if anyone has brought this up yet, but I think
searching (or search results) should be improved. By this I mean, when you search for an item in user shops (top bar), and you spell a word incorrectly, instead of a "not available" result, have a "do you mean this: ____" with a hyperlink to that item.
This might be some confusing wording, sorry :P
Personally I think it would be much more efficient for those who either have spelling problems (like me) or who don't know the exact name of the item (like in item database search, you have to know the exact name of the item). For example, it took me a while to search for Neanderthal LeTainted because I kept on spelling neanderthal wrong. And another example is Madigans Squishy. I kept on putting an apostrophe in the word [madigan's] and it was extremely frustrating.
Support? =)
