Assalamu alaikum
It would be great if the mistakes screen can have a button you can click and go directly to that ayah so you can re-recite it with the ayah hidden. Right now it's difficult to try to test yourself on the verses you said wrong.
An even better thing would be if, after we finish a blind recitation session, we can click on a button (e.g. "review mistakes") which would send us to the page with the first mistake we made, with that ayah hidden so we can redo it, then there would be a "next" button we click to go to next mistake location, and so on.
This can also be more automatized where if we get the previously mistaken verse correct this time, Tarteel would automatically move to the next mistake. Otherwise, it would stay on the same page so we can repeat the verse until we get it right.
Jazakum Allah khairan
