Campfire Smoke

I think campfire smoke should be more powerful to guarantee safe environment to harvest bee hive or nest without aggravated the bees inside, it should penetrate 2 or 3 blocks away with haybale underneath it. Because you know, I'm trying to make an automatic crop farm with automatic bee farm so the crops could grow faster, but sometimes my bee farm didn't work properly and I have to harvest it manually to make it work again. Sometimes minecart with hopper didn't collect the honey but dispenser did, when observer giving signal to dispenser, it can't collect honey because there's a bottle full of honey. The observer couldn't detect bee hive or nest when it's full with honey even if the bee's goes in and out. I hope you consider about it.
