It usually does what is says. Here are the issues I encountered, in order of importance:
- It doesn't work in IE11 (Edge mode). The preview windows pops-up but the content is missing. Content added with the settings panel is visible though. It seems like in IE the plugin misses the target element.
- It doesn't use the CSS styling of the theme in use, as claimed (tried on Firefox 26). It does use though any CSS set in the settings (but not Google Fonts).
- Some times, for unknown reason, it wanted to print the entire page. I had to repeat the process to succeed.
Without issues #1 and #2, I can easily give a 5 star.
