I've been using the handwriting feature more when I'm on mobile, but the size of the screen makes it difficult to tell the difference between similar characters like ロ & 口, へ & ヘ, and タ & 夕 when they appear as suggestions. It would be handy to have an option to filter for which type of character I'm writing, or otherwise mark the suggestions as hiragana/katakana/kanji/etc. so it's more obvious which characters are being suggested.
