How It Works
This WordPress plugin displays a mini preview window on the edit post or edit page screen.
Mini Preview sits in the Page or Post tab when you are editing a page or post in WordPress.
Buttons above the preview window provide for Refresh, various Display Sizes, and Preview in New Tab.
The preview window is a fully-functional, interactive mini browser showing exactly what the page will look like, except in minature.
For quick access to the Mini Preview window, use CTRL+SHIFT+P or CMD+SHIFT+P (ALT+SHIFT+P or OPT+SHIFT+P for Firefox).
