A mode that allows you to specify and test input values while editing the chip.
when making a somewhat complex block-based chip, there's usually some missteps that need to be found in order to ensure proper operational procedures - but spawning and editing your vehicle multiple times is rather bothersome.
the amendmend to such a thing would be a simplified compliator built into the block system that can simulate the chip's intended usage through user-given input, even just booleans would be enough, but numbers and static video could work too.
essentially, a mode that simulates continuous usage with timers/capacitors included - highlighting blocks that return true on given input, maybe even by selecting blocks to return true manually.
