Some Suggestion about kick offlline system, to add a timer

Hi supercell, tnx for giving us this nice update, I really love it, just a little suggestion:

As you know, so many players play this game so long so you set to kick us offline after 3 hours, for me this is ok,but here is a problem, ususally when I boost my heroes, my spell factory... and I've been kicked, so can you please add a timer for us that we can see how long we can still be online? :o
Thank you SC for giving us this marvellous game! :thumbsup:
