I often find word with some helper I don't recognize or conjugation form that I want to review. Most don't have a grammar link at the bottom. It would be awesome if:
1. Each helper had a grammar entry, with example sentences and ~what it generally means in a sentence
2. The grammar entry was linked. Even better if the description next to the conjugated word linked.
The example here is Conjecture, which I couldn't find defined in the dictionary. Would be awesome for "If/when" to be a link for "たら" and "conjecture" to also be a link. It is fine if they remain grey.
Example with grammar at bottom. Would still be awesome if te form was also linked.
I don't mind the grey text, maybe even just add underline when clickable. Easy to look past if you don't need it. As long as it stays less contrasted than the main content, should be fine. Maybe a dull blue, if not grey.
A simple improvement even without linking could be to just always drop it to the second line, with a "<br>"
