This is something that has been nagging be for a while, especially after I figured out circuit controlled throwers. Using signals with Renai is genuinely really fun, especially for the balance between efficiency and silliness. This is a (hopefully) simple feature that I think would open up a lot of opportunities with circuit pads and make some interesting and very chaotic stuff possible.
P.S. If you are concerned about game balance for throughput, the game's built-in UPS will do that!
