The main reason I fell in love with the SmartMoving mod was because you could crawl into wiring shafts made with microblocks back when RedPower was still a thing.

Sadly Project Red is repeating the same issue RP2 had (and fixed) which was that wiring microblocks were not considered ledges which you could hold onto with SmartMoving.

So for example if you have a shaft like this: http://imgur.com/a/TPP8F
You would be unable to hold onto the upper ledge to crawl out because there's no edge as far as SmartMoving is concerned :<

I also don't remember whenever or not RP2 let you crawl in cover made 1x1 shafts, but if it'd be cool if that could be also added.
