QOL change. Queue items you know you are going to buy.
By that I mean that you can select items, and queue them so that when you back, it auto purchases. Maybe add a notification when you have enough gold to buy them.
Less time in the shop looking around for something, more time in lane.
*Ding! you have enough gold for Phage, 2 health pots and a pink" back you land at the fountain and its auto purchases them, and TP back to lane.
you can add/remove items from the queue at any time.
