Adds a [post_thumbnail] shortcode for use with wordpress post thumbnails. Size can also be set using [post_thumbnail size=”XXXX”]. (You can call the function directly in your theme with <code><?php post_thumbnail('size=thumbnail');?></code>.)
Just insert the shortcode into any post’s content and when it will be replaced with the featured image.
This works only with the featured images introduced in WordPress 2.9.

Forget About Shortcode (FASC) Buttons are a visual way to add CSS buttons in the rich text editor and to your themes. Instead of adding shortcodes in the post editor, you insert real, styled buttons – making the process of adding buttons to your posts and pages much more natural whilst improving the appearance and usability of the post editor.

FASC Buttons tries to be as clean as possible with the html, only using data attributes for necessary features – the buttons you use in the post editor use the exact same classes as on the front end of your site with no extra or hidden markup to make them behave this way.

Forget About Shortcode Buttons

... and this has it. Works exactly as advertised and is WYSIWYG. In edit mode, the buttons don't shrink when they receive focus, which I've seen on other plugins. There are a wide variety of choices for appearance, and the icons feature is an excellent addition. It just works.

I look for ease of use...
