Not quite it.Probably remember the last tab that was open after closing chrome
How to trigger that? This setting is strange. Not even Google support knows anything about it.I can't reproduce it right now, but when that setting is on, under certain circumstances when opening Chrome, it'll show on the New Tab page an option to continue with the last tab you had open.
Actually I think thats it. I have gotten a window to acces the page in Chrome homepage, I don't know how to trigger this.I'll have to keep an eye out for the circumstances when it shows up.
