Though the description says that this plugin exists, and the screenshots show the emoticon button, there is no such plugin on the "Configure Editor Plugins" list. So what happened to the Emoticon plugin?
Also, one important (for me) button that isn't included is the Shortcodes Select Button and the ability to enable the linebreak shortcode. These are available in Ultimate TinyMCE, which is what I'm presently using, but that plugin doesn't have the option of rearranging buttons (unless I pay for it) or the ability to set different configurations for administrators, editors, subscribers, etc. I'm assuming that I can't use both that plugin and this one at the same time.
