I have Nova Launcher working on my PC. Here's what I did :
1 Installed Nova Launcher from Play
2 (ROOT REQUIRED) Used SDMaid App Control to freeze "Launcher" , and then "My Desktop"
3. When prompted, selected "Nova Launcher"
Use Apps Settings to set Nova Launcher to full-screen and you can then use custom wallpapers.
Performance seems close to expected.
Thanks to @HypoTurtle on XDA Forums for the help.
1- Scrooling in app drawer doesnt work.
2- If you change the desktop settings in Nova Launcher Settings, app confuses and everything screw each other.
3- Both live and image wallpapers cant be set to desktop. Just black screen.
4- Some widgets are buggy, while some are ok.
Tesla unread counter plugin works though. In general it doesnt worth to install.
Anyway, thanks for info.
