I think this is going to be really great game with just a little more precision.
1) Don't let items set to be auto sold/refined to reach inventory, because it will sort all groups of items in another order (with sort option checked) and if I'm killing an elite creature per hit than clicking the proper item is pretty tricky and see a tooltip with stats is almost impossible.
2) Button "refine all" only refine random half of the items and when in same situation it will refine new items as well as the old ones. (I didn't used "sell all" button so I can't tell if it does same but it's pretty expectable)
3) Maybe somewhere between equipped items and list of actions make some label to write stats of highlighted item.
4) Import/Export option would be really nice.
Thanks for a game, I really enjoying the graphics. Really nice pictures of creatures, almost makes me feel I'm playing MtG.
