Now here me out, in some dictionaries the na-adjective (a.k.a. Adjectival nouns) end in な in dictionary form. (for example in Tuttle publishing’s Essential Japanese Grammar). I want this feature because it would make it much easier to identify na-adjectives, helping me memorize even the ones that end in い (like きれいな) which can be easy to mix up with I-adjectives, not to mention lets me not mistake them for normal nouns. After all, we already have to type “to” before all verbs.
edit: I totally meant something optional such as a script or a toggle (though I doubt the devs would bother since this is a mere gripe)
