[Suggestion] Redo the merchant screen
As it stands, buying and selling equipment/stuff is very very painful.
You can't see what you have.
If you double click on something, you buy it twice but get zero feedback.
The whole screen needs redoing in order to be usable.
It's mandatory that one can
1) See what they already have.
2) Be able to cancel if they mis-clicked.
Even simple games like this one have better trade interfaces.
It would also be great to have an intuitive way of moving items between party members. Right now, it's rather unintuitive. If you're doing it RPG-like, go the whole way and provide an equipment/inventory screen.
