There is no doubt, b2evolution is great and fantastic!Mainly because my BLOG used for students and based on entertainment more, so I wrote a music bar widget. It's advantage is simple and convenient, the drawback is obvious, when the user clicks on a link, it will interrupt the music player to re-start.Frankly this is not a good design, but with my current level of programming, there is no way to solve.Iframe Perhaps it can, but it will mostly change the template code.

If evoskin able to generate an IFrame framework to place the music player, the other link click of the page will not affect it,! For the users of the program, who should be the most convenient!
