Hi @PhilHibbs,
For the home screen:
you probably have to install a app to get a winged or app icon available to places on your homescreen.
i totally understand your struggle with those apps, lots of them are loaded with all kinds of nonsense.
there are better ones available, i like this one:
you can remove the advertisements in the settings and set the app to directly turn on the light after opening the app. that did work for me. no ignoring things after that.
for the lock screen:
is this option available in the nova launcher?
i expect it will. its not effected by the installed Olauncher in my case.
greetings
Tom
