I think the multiple item on inserter thing should be like the stack size upgrade, or a seperate belt stack size upgrade, and when picking up items, have options like:
pick up extra item if time to do so < x
pick x items per time(x would obviousely have a max)

sorry for the bad english

I had some ideas for the Pay2Play / Pay2Enjoy idea:
- maybe make the free version an extended demo.
- make research cost money to unlock and science packs to activate :mrgreen: . it would make the game fun, but would make people want the full game or to buy resources.
- only allow 1-2 save slots ...
