I think it would be a good idea, to practice our vocab/learning, to create at least a few paragraphs of text for each level to show what users can read once they know their kanji from that level.
This contextualizes, gives really great practice opportunities, and would assist with retention.
Could be, but not all that different from the current examples, which aren’t necessarily tailored to your WK level to any noticeable degree. I’m just noticing that I will lose certain kanji I don’t tend to see in the reading I do on my own, and I was wishing for some way to continually refresh myself while getting used to reading.
