Hi.
I saw the very good suggestion about the power poles and though : why not applying that to splitters too ?
the suggestion is to be able to build a splitter over another one as it is possible with conveyor belts.
I know there are not a lot of types of splitters, but I'm sure it would be very useful when we'll have to replace a normal splitter with programmable splitter a dozen of times to optimize our production. It would be nicer than removing it, then removing the belts that hinder, then building the new splitter, then building the belts we removed,... for each splitter.
