I’m wondering if it’s possible, from an app, to add / customize the informations shown in the lock screen. The example i have in mind is the media players, which shows the play / pause / next buttons. My understanding is that is done via the mpris media player, which is a system component, not directly by apps, so it’s not a good example, but I would like to add some buttons on the lock screen, in kinda the same way.
It will probably not be for harbour (it can understandably be forbidden until a proper authorization mechanism exists), but for openrepos.
Any ideas / pointers ?
