Add some sort of locking for the main screen

[Kampi]

Shall we add some sort of locking for the watchface to disable the opening of the main menu, etc.?

Never had this issue, but we can add it if it's needed. Got a proposed way to do it?

Not yet. Have this feature on my fitness tracker and it´s quite nice. A simple timeout with an unlocking by swiping up. Guess we have to change a bit to make it work.
