Describe the feature

Previous unit frame addons I’ve used include an optional black bar (like Pitbull’s “Blank Space” or ElvUI’s “Information Panel”) that players typically use for names and info. Personally, it greatly improves readability for me, as my eyesight isn’t the best. Small features like this help more than they might seem and if it's at all possible I’d really appreciate seeing something similar added!

Describe the implementation

I would like an option to add a blank bar (preferably black or with the ability to choose the color) to the unit frame.
