While reading the description I see a lot of neat stuff that solves some ussues I've had with Factorio building. Some things are missing though ^^
I haven't yet tried PEV though...

Suggestions:

• If you have something in your hand and it runs out (bots took it or you placed them all down), automaticallly insert a blueprint of that item into the players hand immediatly so you can just keep building. The blueprint just disappears when you Q I guess.
• When you try to build/mine something outside your reach, ghost place/decon plan it automatically instead of failing. I tried to do this myself earlier but I hit a lot of limitations in the lua mod api so I made something hacky that sort of worked but not as fluently as I wanted it. I got bored and gave up. So I know it's not as easy at it sounds.
• https://mods.factorio.com/mods/mickael9/cut-and-paste is a neat mod. But the copy planner returns to main inventory instead of toolbar, and you can only copy once. It could be improved and would be better if it was integrated with PEV. Hotkeys for the Copy and Cut tools could also be neat? Or maybe I should just tel CaP authour to fix his mod and leave it at that?

• If you build an item and it uses the last item you have it instantly creates a blueprint of it.
• Not as easy as it sounds.
• I will look at this mod later and see what needs to be done for better support.

Oh, nice :]

Yeah, ik :/

Sounds good.

"If you build an item and it uses the last item you have it instantly creates a blueprint of it." Can you turn this "feature" off ?
