and many others that i haven't tested yet(not all with direct apply from the icon pack).

Notes :
1. Wallpapers will be stored inside the Pictures/Matericons/wallpaper folder
2.If you are using Smart Launcher, apply icons from Matericons, NOT VIA LAUNCHER SETTINGS!
3. If you want to get your icons themed faster, get Prime Icon Request. Is a lot of requests and i can't do all in one update for example.
4. LG Home is unstable with icon packs. Try to install another launcher ( NOVA, APEX ) or don't buy it if you want to use them with LG Home!


If you have troubles with the application, icons, you don't like how an icon looks or anything else, contact me on HANGOUTS or GMAIL(hangouts is a better way for comunnication than gmail).
