Is it Possible to Use Live Preview with Global Settings I know that out of the box one cannot use Live Preview with Global Settings.  I am wondering if it is possible to write a plugin or in some other manner get Live Preview to work with Global Settings.
Anything's possible, but not without hacking core files, which isn't recommended.

By default, global settings don't even have the concept of a "template", which is a fundamental part of getting a Live Preview request to work.
