I'm still on 8.5 awaiting update due shortly apparently, I've found I've had to go back to stock launcher to change wallpaper and style colours to match what wall I'm using on SL before I set wall through SL . To be honest I actually find stock launcher looks very good with a few tweaks here and there, so I'm sort of swaying back and forth..with a bit of Niagara in between..which seems to work well for me lol
