I've tested the rest of the library settings editor.
The initial display is now alphabetical and the column sort works great! The filter and context location work, Import/Export, and Revert all work as expected.
The Edit pop up looks good with the button colours fixed.
We're down to just the two outstanding issues: True/False doesn't work as expected and only Global Admin accounts can see library settings.
