Some notes:


 * Changing specific backgrounds works on the preview buttons, although I could be mistaken.
 * The classic source editor sometimes refuses to accept pressing the up and down buttons to navigate through text.
 * On wikis where Message Walls aren't enabled, the link sends me to my message wall rather than my talk page.
