What the OP asked was not to label the section but the viewport that is displaying the section.

Another thing that you cannot control is the opacity/color of the section plane, if you decide to show sections, or the linestyle and symbol of the section lines.

All of these features you seek have been asked as feature requests before. I hope they make them happen.

Looks like a pain to clean! But I guess if you can afford it you aren't the one cleaning it!

Thanks! I'll give it a shot and see how it works.

Best,
Chris
