So, here’s a hypothetical scenario.
You’re working through your reviews, and you realise that you made a mistake, or for some other reason want to check the info on a particular kanji/vocab etc, but you can’t right now because you’re in the middle of a review session. (Besides, the Info button is greyed out).
What if the Info button became a “Check Info Later” button?
Then, after your session, the marked items are displayed for you to check
and/or they’re added to your Critical Condition list (regardless of percentage score)
Yeah, you could open Google or something in a new tab.
But this way it’s all self-contained, and you can focus on your task.
