What's going on in upper right corner window? Is that a piece of parchment or like a brown sack? I think that window looks odd since it isn't aligned with anything in the column.
It's a sack, but that's a graphic the user can choose. That window is for the "loot" inventory. Or chest, or whatever. Basically, if you get too many items and want to throw one away, it goes to that inventory. It could also be any other type of inventory though, so if you're accessing a chest for instance, you can take stuff out of it and put stuff into it and its permanent.
Also, I moved things around a little bit because I thought the alignment looked off too. I'm not going to change it, because it is a necessary window, but I think this layout makes it less odd looking.
And I am allowing the user to change the height, but only between 96 and 128 - the Info window couldn't handle anything greater than 128. <96 is OK too, but not if they are using default sprites, though actually, it will shrink them accordingly.
