I suggest to upgrade the inspect skill once at skill 100:
When at grandmaster skill you should be able to inspect your trade as soon as you see it.
So that a forrester can inspect trees and instead of getting the inspect option, it simply states the stats of the tree
A carpenter would have the same, but with cut logs and carpentry crafted items, seeing Quality, hitpoints and remaining wood in a log
And so on - A miner would see the quality of iron in a mine, a farmer would see the quality of soil and planted crop
