I use a lot of multi-requester stations where there are many items to provide from a single LTN station. I run out of signal slots so I have to add regular combinators which means I have to do math on the various stack sizes of items in the game to meet the request threshold. It would be great if I had more signal slots that automatically did the math for me. So, I propose more signal slots, or another combinator that gives us more signal slots that does the math for us :)
