Make shift+q allow you to get a ghost of the item under your cursour in your hand.What ?
make shift+q give the player a ghost of the item under your cursour to be put in your hand. This will then allow you to place ghost entities of that item on the map without needing to have this item in your inventory.Why ?
In late game, if you want your use map view and see some tiny mistake you would like to make your robots fixed, you really dont want to need to have this item in your inventory to do that. single entity blueprints work for this, but are quite annoying.This is especially the case, if you play with a modset that increases the number of different entities by far like eg seablock.
