When I start a new year I just make a new folder and copy across just the files that are named xlights........xml. There will be 3 or 4 of them. That gives you all the models, your network setup, and your keybindings. Then just copy the music files you want. the way I do it is to have one folder named xlights and then underneath that folder I have many other folders that I just switch to as needed using the setup tab. I have Halloween 2014, Christmas 2014, Christmas 2015, Halloween per kulp, tests per Jon Back, etc. When someone shares a sequence and their setup info, you put it into a new folder, switch to that folder and look at the shared stuff using their models and preview. If you like the sequence you copy just the xml file into your own folder, switch back to it via the setup tab and then open the xml file going thru the model matchup/skip questions and voila you have a sequence you can now see on your own display and edit to your liking.
