Exit out of "learn from your mistakes"

I really like the "learn from your mistakes feature in the analysis board. However, I very often want to go over the game again with the computer, which can't be done while "learn from your mistakes" is open. I seem to remember that in v1, there was an x in the top right, but that isn't there anymore. It's a small thing, but it crosses my mind every time I have to refresh the page.

Click the "learn from your mistakes" button again, the same one you click to start it. It should deactivate the feature.
