Pretty basic request: When you attempt to "Lift" a cart, you will instead begin to "Pull Cart". If you "Lift" it again you will stop pulling the cart. Remove the flower menu and instead right clicking a cart will always open it.
Reasoning: Heavy use of the cart is a lot of clicking, and indeed a lot of mis-clicking like opening the cart instead of pulling it. Lifting may be confusing the first time you use a cart, but I think it would simplify it's use greatly.
