In my main xlights data folder I have many sub folders. 2014 Christmas, 2015 Christmas, 2015 Halloween, and now there is one for 2016 Christmas. I just copy everything from 2015 to the 2016 folder and then start making changes. You just go to setup and change folder. That is also the way to look at sequences that are shared, make a folder and copy all the shared stuff to it. If there is no xlights network shared, just make add 16 or 32 e1.31 universes. It does not make any difference what you put in there as you are just going to look at it. To use it you would import it into your own folder using the import function.
