I don't know how hard this would be to implement, but it would be pretty awesome if you could add a feature to character inventory that allows us to lock an item to a particular block, so that if you use it, it returns to the particular block.
For example, if you keep scrolls of Greater Heroism in the first block of your second inventory tab, then after you use one of them, the stack of scrolls would automatically go back to the first block of your second inventory tab.
Would be a nifty change.
