Fix device name hidden by dimming controls

[stevenrw]

Please fix the fact that the device name is partially hidden when dimming controls are displayed on the device.
AND... Make the device name longer than 15.

I with you there on both items, my short term memory is challenged when I forget the device I am actually working with when it's hidden.

And there is plenty of room on the screen of most devices to get those names up to 25 characters.
