i did it Sorry for being a little off the forum (I'm barely having free time lately). About what you want, I think the most easy solution is to "clone" (copy and paste) the code of the "Select" or "Sort" buttons (from the Live 3 template), and add the buttons you want, copying only the functions found on the default template. I'm not good editing templates, so, it's not an easy task for me (it could take me a lot of time, which I currently don't have). May be you or someone else here could do this.
