I learned that laying the song out in a single chorus can be very helpful. This includes the 1st/2nd endings, repeats, intro, tags, etc. Once that is done, you can 'clean' up the arrangement by defining those items if desired. FWIW, I only use those for obtaining lead sheets - where getting the song on a single page is important. My actual performance songs are Unfolded.

Also, if you intend to use Realband at some point, it will be easier with an Unfolded song.
