Not sure if brought up before, but assessing/comparing the weights of two things in hands, should not be hard for anyone.
Doesn't make sense to me I can't know if one rock/sword/etc. is heavier than the other held.
I would like to see the value command allow for determining weight more accurately for those without the value skill.
Edit to add: Or, at least, a "compare" command. This sword is heavier than that sword, sort of thing.
