Group together items with a no. indicator for how many you have so the items area is less cluttered
The items getting tossed randomly on the side can get really cluttered and confusing to see exactly what items are at your disposal. I think it would look nicer if the different items each had their own respective spot in the items area, then when you own 2 or more of an item it just adds a number above like x2 or x3 to indicate how many you have. It would neaten up the side of the board and look less cluttered.
