Hi,
I think it would make sense to be able to display a noun's classifier(s), ordered from the most common used to the least common used, next to the other information. For example MDGB has this.

i also thing, dedicated classifier training would be nice, but thats not so important.
having the classifiers displayed would already help a lot.
