Has this always been there?

When I click on an existing event in my calendar and hover the mouse over the "creator" the picture that I have in Gmail for that contact pops up with their name and clickable email address above it.

I don't remember noticing that before, but I may have missed it.

I've never seen that before but I don't remember ever hovering over the names before either. (Surely I would've noticed it if it was there before though... wouldn't I?)

I think it's new.

It has been there for a few months.
