1) Quiet time and profiles - these seem to have been removed in KitKat. They were stock features in JellyBean.
2) LED notification customization.
3) DPI settings.
The last 2 were features of slim. I'm currently running stock, rooted + Xposed with GravityBox. Is there any way to get these features without flashing a custom ROM? I know about light flow, but I was looking to see if this could be done with an Xsposed module.
