I've been using this plugin for more than a year. Now, I've implemented it for my new Joomla 3.1.5 site. Easy to input a mp3 player in between texts in articles is helping for audio illustration in my educational websites.
However, one suggestion to the developer is that if there would be an option to change the color style, it could be even better.
This is what I wanted, really great plugin. You can select the position either top or bottom or both, I like the toolbar very much. Sharing to facebook and other websites, facebook like button, google plus button and more..Nice, I appreciate your work.
