a filter tunnel with a logic on/off state would be great, and the splitter is kinda finnicky to place on a line when you want to siphon excess materials off a different conveyor belt, having a lopsided splitter with an input on its side would be a gamechanger for my factory
Edit: oh and absolutely, wish there was a way to reverse latch functionality
Another edit: a logic blinker would be great - activates for a frame or ten frames when receiving a logic state change
