Bliss: Lock apps on home screens and prevent their deletion

For Bliss I would wish to allow optionally to lock the placement of the app icons and prevent deletion in the usual way. As long as Bliss has no own settings, I'd propose to put this options into Settings>Screen ie Settings>Apps

Despite the fact that I am fine with the current situation, I acknowledge, that for certain users (i.e. elders), it could be really helpful if relocation or deletion by mistake could be prevented in a simple way.
