Possible feature? Bookmarking lessons for further review

[John.Red]

Often, I'll take a lesson on my language tree and pass it, but I feel like I wasn't quite as confident in it as I'd like to be.

Is there any way I could put a "Further review" mark on it to remind myself to come back and strengthen that skill?

Perhaps this can already be sort of achieved by looking at the "Vocabulary" tab, but it seems like it could be more effective somehow.
