I don´t know if it has been suggested before or not but I´ll write it anyways:
I would love to see a more categorized blacksmithing screen. It´s ok as it looks now but it would be way better if you would put the stuff for each class together instead of everything scattered around, sorted by the blacksmithing level, e.g. when you select Armors, you will firstly see Warrior stuff, then Archers stuff, then mages stuff, each sorted by blacksmithing level. It would make a much nicer overview of what you actually have to look up for yourself.
Any while I´m here, are there more mage equipment coming aswell? I guess everyone by now knows, mages are focused on fire too much. Theres little to none for the other 3 elements, except a few things maybe (As far as I´ve seen it yet). Alot of potential right there, not only with mage equipment, but I havent focused on the warrior/archer equipment yet but maybe in the future I´ll take a in-depth look into those aswell (I got tons of idea in my head lol, but in the end it´s up to you developers to do that stuff)
Cheers
