i wish to add some more stuff of my own in the code of my forum,for example my music player how can i do that? and if i cant could it possibly be something avaliable in the next updates?

This is the code i wish to add


<!-- SCM Music Player http://scmplayer.net -->
<script type="text/javascript" src="http://scmplayer.net/script.js"
data-config="{'skin':'skins/cyber/skin.css','volume':50,'autoplay':false,'shuffle':false,'repeat':1,'placement':'top','showplaylist':false,'playlist':[{'title':'Gothminister - The Calling','url':'https://www.youtube.com/watch?v=eIiniM6WvUw&index=12&list=RDMFhEHlNT4iM'},{'title':'Manowar Warriors of The World ','url':'https://www.youtube.com/watch?v=FVXR4YWup_E'}]}" ></script>
<!-- SCM Music Player script end -->


My aim is to be able to add a music theme to my forum is it possible?

Also apart from that how can i change this background? http://prntscr.com/8h1s8k more freedom in our changes would be awesome...even if you give us the ability to modify code...please
