I mostly do wanikani on my mobile device as I commute a lot and I noticed a thing that I think could be improved.
When you get a review right, the keyboard disappears and you have to move your finger up to click next since your enter key is gone. This was okay before since I had a small phone, but now since most phones are becoming bigger and “taller”, it’s becoming really uncomfortable.
Maybe moving the next button lower on the screen so that it is hidden when the keyboard is open would be an easy improvement on mobile?
