Missed challenge

That would be great to view missed challenges, specifically when I am not at my computer and cannot immediately respond to them. It would be helpful to see who sent the challenge so that I can contact them (especially if that was a friend of mine) at a later time.

I agree with you.

Could you create a github account and request this at github.com/lichess-org/lila/issues

It wouldn't be a super high priority but it's a cool idea and it's easy for those to get lost in forum threads.
