Listener Circuit Board/Activation Board
A circuit board/panel that only activates when a machine adjacent next to it successfully activates. This would allow for more precise activations for machines instead of just having them be 'on' by default and awaiting their toggle condition.
This was one of my ideas from my reddit post on ways to expand automation: https://www.reddit.com/r/CoreKeeperGame/comments/1t71uo2/ideas_for_expanding_automation/
I found myself wanting this for crop farms. When needing to replenish seeds from golden crops, you could detect when a golden crop on the output line is picked up and then take a regular crop from the output line to send back to the seed extractor to replenish the seeds that were lost by the golden crop.
