Sentences as objects tips and notes
In the tips and notes for sentences as objects, the construction is described as "how Klingons do the equivalent of subordinate clauses..." I recommend changing this terminology: The Klingon Dictionary uses the phrase subordinate clause to refer to the clauses created by syntactic verbal suffixes (except for -'a', -wI', and, if it had been included in the first edition, -ghach) as subordinate clauses. Instead of saying "This skill will teach you how Klingons do the equivalent of subordinate clauses..." you might want to say "This skill will teach you how Klingons use one sentence as the object of another sentence," or something like that.
You might also want to note that, as TKD says, sentences as objects "are used primarily, though not exclusively, with verbs of thinking or observation."
Finally, you should mention here that the aspect suffixes are not allowed on the verb of the second sentence.
