But some things are. It would be really nice to see a more stripped down version of this mod that removed a lot of things that Factorio now in the base game. For example, if you hit 'Q' over a ghost in Factorio now, you do get the entity to place. If you press 'Q' over something you don't have in your inventory, you get a ghost. And the cut & paste tool removes a lot of the usefulness of the blueprint stuff.
But the dolly is still really useful, and possibly some other things.
The only reason I think this is a good idea is that Picker is such an extensive mod with so many different features. It's kind of overwhelming and ends up taking up a large swath of my keyboard if I try to use it all.
