There are a few pain points related to Assemblers in current Factorio version.
1. Currently when you copy paste a recipe from an Assembler to a Requester chest, it copies based on 30 seconds worth of crafting resources. While its a great initiative, but can be too developer opinionated sometimes. It would be nice if there is a special paste shortcut (lets imagine CTRL+SHIFT+left Click). On using this special paste on a requester chest, it pastes 1x the amount of resources required (instead of 30 seconds worth). And then if you so the special paste again, it simply adds up the current requests with the new paste. This way we can have 2 ASMs with different recipes and we can special paste both of them into the same requester chest, and the chest can serve both ASMs.
2. Currently ASMs cannot be read by a circuit network on multiple needs:
a) 1st need is: a circuit network should be able to read the list of required ingredients for the ASM. That way we can have set those signals to requester chests based on our own multiplier (or other custom logic). This can also help with intelligent sushi builds.
b) 2nd need is: a circuit network should be able to read what ingredient items are currently sitting in the Assemblers. That way we will be able to make sushi builds in a more effective manner. Also helps with optimizing expensive builds like RCUs.
c) 3rd need is: a circuit network should be able to read the status of the Assembler. Nice to know if its "Working" or "Power low" or "Waiting for destination space" or "waiting for ingredients".
I am hoping some of these issues gets addressed in 2.0

2a) Reading ingredients (and their count) of the current active recipe will be the in 2.0/Spaced Out.
2c) WIll partly be in 2.0/Spaced Out. Namingly if it is currently working (as static signal) or just done with the current recipe (1-tick signal).
