Feature request: efficiency score

[seraphine]

I just completed the 3 Pin OR level with a monstrous circuit of 5 OR gates (2 intermediate layers of 3 and 2...), and I passed the level. But then I thought it should have an easier solution so I solved it with 3 OR gates (2 -> 1). And then once again realized I can reduce to just 2 or gates. But the level just told me I passed at the first try. It would be really nice to get a score or info about how many components the most efficient build uses. (of course some components are composites so are more "expensive" than others.

Already in the game, it just doesn't show up until later.
