While trying out a new version of the UsabilityInitiative extension, I found that some variables that can be set in LocalSettings.php are not documented. They should be added to the README file.
Specifically, at least the following settings are undocumented:
$wgDefaultUserOptions['wikieditor-highlight'] = 1;
$wgDefaultUserOptions['wikieditor-preview'] = 1;
$wgDefaultUserOptions['usebetatoolbar'] = 1;
$wgDefaultUserOptions['usebetatoolbar-cgd'] = 1;
$wgNavigableTOCCollapseEnable = true;
$wgNavigableTOCResizable = true;
There may be more which I didn't find.
