Where is align objects button in a customized toolbar?

In the latest version of Acrobat I can't seem to find the "align objects" button when trying to customize the toolbar. Was it removed?

Here is what I mean - a screenshot from the prev version:

Also, old bug still not fixed - you still can't switch between doucment tabs when clicking the very top part of a tab, like you can in browsers. In Acrobat, nothing happens when you do this.
