Feature Request: Night Mode

[c0wb0y-crypt0]

Is your feature request related to a problem? Please describe.
Not a problem, simply a convenience request. May attempt to work on this feature myself.

Describe the solution you'd like
Add a Night/Day mode button in the left hand navigation, above the Home Button, or perhaps at the bottom.

Describe alternatives you've considered
Adding an option under Settings > General Configuration instead of on the primary navigation menu.
