Just wrote my first ever WordPress plugin.
A while back I wrote about using the preview in WordPress when writing long posts and how to open it in a new window or tab.
Well, this plugin creates a handy link that you can use to do just that - one click to open a preview of your post in a new window. It only works after you’ve pressed the Save and Continue Editing button at least once, as WP doesn’t generate a preview before that. Every time you save the post after that, you’ll need to reload the window/tab containing your preview to keep it up-to-date.
It’s not much, but it’s a start.
By the way, this is pretty hacky too.

Installed on FOSSwire.
