Navigation Pane Options...

By right mouse click on the Navigation Pane on the title bar (*All Access Objects*) you can get to options like... Category, Sort, removing (or showing) the *Search Bar* and more...
Or you can hide the Navigation Pane entirely by unchecking ‘Display Navigation Pane’ under Navigation on the Options menu.  Now, if after all the this you still can't adjust to the Navigation Pane, have a look here...

The Navigation Pane replaces the Database Container found in Access 2003 and lower.  When you open a database it is permanently docked to the left.  Below are a few of the things you can do via the Navigation Pane.  Click the letters to jump to the screen shot...
To Show/Hide the Search Bar you can either right mouse click on the Navigation Pane and select/deselect or go to Navigation Options (see * C *) and select/deselect from there.
Change the way you display (view) your Objects

Navigation Options
From here you can select Display Options (*Show Hidden Tables*, *Show System Objects*, as well as, *Show [or Hide] the Search Bar*) and how to open your Objects (*Single or Double Click*).  You can also add Categories and/or Groups...
While you can Sort by many things, sorting by description is gone.  For some of us this was a handy thing as you could put things like *Step 1*, *Step 2* and so on.  Well, you can still do that just using Groups instead.  You can then assing your Object any name you like, such as, *Step 1 - Run this query first*, *Step 2 - Run this Update query second*, etc...
Shutter Open/Close the Navigation Pane
Entering a Description here shows above...
