Is there a way to make all available shortcodes accessible via a drop-down list in the editor similar to the plugin 'AddQuicktag' (see bottom screenshot here: http://wordpress.org/extend/plugins/addquicktag/screenshots/)?
I think this is slightly more user-friendly/intuitive way to call a shortcode and would save a step the user has to go through in order to input a shortcode. They are required to select from a drop-down menu anyway in the Shortcodes UI so why not bring that to the editor panel or have an option select either 'buttons' or 'drop-down menu'?
Highlighting only as a potential final tweak to an already brilliant plugin! Thanks for putting in the time to develop.
