for single and bulk move, the new vanilla cut/copy/paste CAN be an alternative and is less "cheaty", but (as billbo already said) it requires to have bots and also moves around lots of items (including thousands or millions of items from chests, warehouses, etc !?). when creating or modifying combinator setups, won't the vanilla functions copy/restore only those colored wires that are IN that temporary blueprint, but lose all wires that connect that group of entities with other (non moved) entities ?
since i prefer nanobots over some mod that gives me bots for the game start to be "less cheaty", and because of the other problems when really rebuilding everything instead of moving, i probably still would need this functionality, also (or especially) when creating new combinator setups.
