Better Preview provides you a preview button for the article you are working on. See what the article will look like before saving or publishing it!
ADVANCED VIEW SITE
Better Preview also changes the way the 'View site' link in your administrator works. It will make that link go to the frontend equivalent of that page. It will also display links to any parent pages (like parent category pages when editing an article).

Peter's support is also Top-Notch. He responded directly to emails and even helped me figure out an issue I was having.
I just started using Real Preview (free version) and it does what it says, cleanly and without problems. My first reaction when using it to preview an article was, "Thank goodness!"
Note - articles need to be saved before they can be reviewed, so perhaps it would be better to do autosave function in this extension or some temporary save with random url (even better).
Running on J1.7.4 PHP 5.2.4 (They recommend PHP 5.3+)
I tend to write pages "off grid" so I can tweak them until they're perfect and this plugin allows me to do this. I used to have to put my site to Offline to do edits when changing live pages. Now I create an off-nav page and use Better Preview, then add it to the site nav structure when it's ready. Such a time saver!
This is one of those essential plugins I add to every single Joomla site I build. Thank you so much, and good show!
"Add to menu" by the same author is another time-saving extension that works great.
You can request features via my forum.
To get the entire url, you can just open the page via the preview link and copy the link from the address bar.
