There was an option when using compact_header but that is now depreciated. I know there are options for lovelace cards but this seems like a good location for a time / date display
On a desktop screen that might be fine, but if you open the frontend on a mobile device, this would be a bad location since it would take up much of the already small space for the view buttons.
Then we would probably need a control flag stored per device. So not as straight forward as it might seem.
@spacegaier Thx appreciate the feedback it should be configurable from the user side. Given that it is not possible at this time I will look for an alternate solution.
