Would REALLY like a Copy Slot option. That way I can setup a slot with all the options I want and then copy it. Very time consuming to have to place each slot then upgrade it. Would also be nice to have a Move option as well.
Another nice thing would be an indicator on each slot if there are new upgrades available on a slot. And this could also lend itself to copy upgrades from one slot to the others of the same type. Anything to reduce the number of clicks to setup slots.
