Diggz Team

I have similar setup and I haven't lost the skin, but if I leave the room for too long after starting up Kodi/Xenon or if I pause while watching a movie and am gone too long, then the screen saver pops up and I have to re-start Kodi/Xenon.

I've been using Diggz Xenon with some addons for a while. Decided to do some poking around and am wondering what Xenon Flavors (skin options) would be used for and what going to the Diggz Skins Portal and switch to a different skin would buy me. A little explanation would be appreciated.
Thanks....
