TL;DR
Reading recipe of assembler.What?
In the menus, where we can set what an assembler should act on the logic wires it is connected. Adding the option, not only to have one tick of a given signal, but also a permanent signal of the set recipe.Why?
In the early days, resources and assemblers are not fully automated. So I set up an assembler ie. crafting logic chests - so an inserter can be active while whatever the assembler is currently producing is lower than a given constant, or set the filter, that only the recipe will be emptied from the assembler and not the cleared items - which is the more important now, since recipe can also changed now. The recipe signal can be passed on to inserters, but the signals can be noisy and this would enable a "cleaner" setup.Also, i think it is more intuitive this way - arguably.
