Newly designed Adobe Acrobat Pro.

First, I want to admit that I am f...... stupid.  The newly redesigned Acrobat Pro was designed to make things even easier to manage my work, except for: why isn't there a visible button ot tab on the navigation bar to "Save Documents" in any files I want them in, or on my desktop, or anyhere in my computer other that the f...... cloud? It is the most complicated task, and time consuming effort to accomplish.
