Good functionality — obscure UI

The functionality of this plugin is great. The ability to time-limit the preview is definitely going to be useful to some people.

The UI of the plugin could use some work. It’s currently buried in a submenu of the Posts menu. From there, you have to choose a draft from a drop-down list. It seems to me that putting the UI on the post’s screen would be better, as that’s where people are when they’re editing that post they want to share with someone else.
