Here is an excellent example of having too few slots(even when trying to optimize as much as possible):
Building a BC Assembly table room(lasers) with Marble on the outside and Abyssal blocks on the inside. So ending up using full size, slabs, covers, strips, nooks of both marble and abyssal. Two kinds of Strengthened glass and Clear glass, Chisel factory blocks and covers. Four different kinds of Project red wires and a load of other random crap. And I had actually just been forced to unload all the BC gates, Structure pipes, pipe wires and stuff.
Constantly a puzzle moving things in and out of hotbar
