Currently I'm working on some software settings screen, and there are a number of features, that could be turned on and off manually, but also kept in kind of 'wait mode'. If a feature is in 'wait mode', the system turns it on and off automatically according to its own needs.
I only managed to come up with two options.
N1. Triple state toggle with icons and maybe tooltip on hover. The weak point is metaphor for 'auto' icon, it seems quite hard to select a convenient one.
N2. Checkbox for automatical turn on/off and standard toggle after it.
As both options are quite weak, I'd appreciate ideas of organizing this information better.
