By default, the only way to see how a new theme looks on your site is to
activate it, making it visible to everyone who visits. With this plugin, it
is possible to view how a new theme looks without activating it.

TODO

Possible future enhancements:

• Add an options screen.
• Allow choice of theme to preview from a known list of installed themes.
• Provide persistent previews by setting a cookie.
• Restrict preview ability by user Roles/Capabilities.
• Child-theme friendliness.

Notes

May not work properly with child themes. This is because it will not be able
to inherit from the parent theme as it normally would.
