QA Regression?
Yes:

Broken:2362994
The import button for most of the general editor settings is grayed out. User is unable to import previous appearance settings.
Update 06-28-2017
A workaround I found in ContentExamples was change something and use the Set as Default option. When the file was checked out of P4 and updated, the Import button appeared. This workaround didn't work for me in a new project however.
1. Launch the editor in QAGame
2. Open Edit>Editor Preferences>Appearance
RESULT: The Import button is grayed out and cannot be used
