Activate GravityBox, reboot.
Configure all GravityBox sections, reboot
Whatever that is not applied via GravityBox, can be applied via The Wings!
GravityBox known bugs is reported in
this thread, most are working.
It should work for other ROMs too. Maybe not RR though, coz RR is too heavily customized and the 'settings' will fight with GravityBox.
It should work great for Lineage 15.1.
Amplify is the real winner here. It allows limiting of system Wakelocks & Alarms.
