It'd be great to have a page index feature where you build each page separately and then play them in any order as many times as you want. For example your song intro may take 4 pages but it's really the same thing over and over so make it one page and then tell the tool to play that 1 page 4 times. This would also allow you to make much longer songs and not be limited to just what you can do in 8 pages.
