What does a check mark on a site thumbnail means? And how does one remove it? I'm using Chrome canary and this check mark has appeared. I don't know why it appeared and what it means? Page is bookmarked but others from here are too but no mark; page isn't saved for offline reading. Any thoughts?
Also how do I remove it?!

It means the site is downloaded for offline viewing. You may have done it by accident but that is what the icon means (unless Google changed the meaning in your Canary build which I find very unlikely).
