What would you think about an option of hiding the tags of a problem when you don't want to see them? I would find it very useful, since I use past contests problems to practice sometimes, and in this case I don't want to see the tags while I read the problem so I don't get biased =)

Alternatively, the tags bar could be initially "closed", then one would click on it to see (or "open") them.

So, what's your opinion?
