As much as I like this, why is it so hard to have tab management that just works? I have six pinned tabs that I always want up. Important things like Gmail, Calendar Drive. Stuff that should never change. I don't want to have to remember to open links in a new tab from pinned tabs. It should know that pinned means pinned.
Perhaps if they enabled group persistence? I'm hoping this rather obvious feature is in there.
My solution has been to use a tab manager with a saved session that I can always recall when my pinned tabs break (such as when Chrome crashes, and loses my session entirely).
