You are right that it can be improved, but I don't know yet how. First of all I don't want to give multiple ways to do one action, as this is very confusing. Thus, all actions on items would have to be done in the inventory window, [drop], [apply], and later [combine]. Maybe there is an elegant way to do this. I also thought about putting equipment and inventory in one window, side to side, as it's pretty wide. But it could look overly complex and be too confusing.
