Sometimes there is an interesting ad (I know, I know I am probably a rare animal being interested) and I don't manage to click quickly enough. There are no way to re-watch the ad, or check for an ad which is over.
I dunno maybe have a directory for the ad which people saw but could not click quick enough, or a button "re-watch advert"... OR a command !ad to be able to re-watch the ad.
My two cent. Although probably nobody want this except me.
Actually I saw an ad I wanted to watch again so something like this would be nice.
