I feel like I've tried to report this before but...
反対/はんたい for example is marked as (Noun/な-adjective) but it's also a suru verb. Jisho says "Noun, Suru verb, Intransitive verb, Noun which may take the genitive case particle 'no', Na-adjective (keiyodoshi)". Since the data is from the same source, the data is probably there, but maybe only up to two parts of speech are shown. I'd like more parts of speech to be shown.
Yeah, I've also noticed that. I've always assumed it was some sort of (legacy) structural limitation. Something that Michael *could* change, but it'd be too much work.
