Title :) Great idea for a mod. I'm finding I have to manually click the button rather than copy-paste the setting on tiles that already have circuit connections.
Rereading this I got worried I need to clarify something: while blueprinting works, what doesn't work (yet 🙏) is when I shift + right click to copy the entity settings, then shift + left click to paste onto another belt
I see -- well I'm just one person, but for what it's worth, I do use copy-paste on entity settings a lot, so I wanted to make sure you were aware it's not working. Of course it's up to you to decide how to prioritize that fix, if you do it at all. Hope that helps and thanks again!
