I would really love to see two things added, one in-game and one at character select.
In-Game:
At the Auction house, the items "know" if I can use them, how about a filter to weed out unusable items so I dont have to look at multiple pages of items I cant use because of race/alignment/etc restrictions? Sure, it'd take some coding and a little work, but i think it'd be a good addition.
Character Selection:
A button to allow changing servers without restarting the client completely. Many other games already offer this and for those who like to bounce between servers, it'd likely be a welcome addition. It'd also require some coding and perhaps even an additional "selection screen" but I believe it might make some players happier. Could even add code to purge the settings from the departed server (a-la restarting to fix the client related lag/crashes from swapping toons)
perhaps these have been brought up before, but if they were i apparently dont have the right search idea in mind.
Regulars have any input? please attempt to be constructive.
