But are there any particular sticky points of grammar that you believe need to be clarified?

The noun suffix -'e' should be more clearly and accurately explained. The existing TKD only calls it "topic," but we know that when put on the object or subject of a "basic sentence" it really means focus. The difference between topic and focus should be explained.

Speaking of which, the matter of whether you can just throw noun'e' at the front of any basic sentence to force contextualizing that sentence in terms of noun should be addressed. If you can, a simple example would suffice. If you can't, a word to that effect should be mentioned.

Oh, and it would be really nice if we got an "official" name for sentences built out of pronouns instead of verbs. Should they be called copulas?

And there should be a note somewhere that when the rules talk about basic "sentences," they really mean any subordinate clauses: purpose clauses, relative clauses, and other subordinate clauses. I can't count how many times someone has challenged me to prove that you can put "sentence" conjunctions between subordinate clauses — there are plenty of examples, but it gets tiresome to show them over and over.
