[UX/UI] Improve the collection "Add" button position

When I add new places to a collection I'm usually lost as I'm searching the "Save" or "Add" button on the right of the popup. I usually see "Close" first and assume that it's autosaved. Then I see it is not and then see the "+Add" button at the left.

It would be easier for me if that button is besides the "Close" button or at the right.

Thanks!
