There were some questions that I saw on the Linear equation word problems skill that I really liked, particularly because the method of approach to which the question was solved was fantastic. I wondered where I could keep those questions,  I could copy them into my notebook (which is not wrong), but I thought that would be tiresome because some of the questions are long and even the explanations are longer. 

So maybe making a, let's say, "favourites" section on my profile where I can see all my saved or "favourited" questions could do me some favor.
