RC14: 'add' plus mark for Custom Metadata panel is too easy to miss

I got excited about discovering this very useful feature, one more fine thing you can find in Scrivener almost-3, for its use to make your own extra information columns in the Outline. Like what I was after, POV…

But it seemed not to work. Reason: as you can see in the image, the ‘+’ icon that would add a field is in a pretty unexpected place, and at no higher contrast than text, which is pretty low-contrast on an ordinary decent but not IPS laptop screen.

Suggestion: Make it bold and up the font size a little, as that would help and take minimal time.

Some juggling of positions for spacing need then, yes.

Of course an actual icon could do better, but you are closing in on release feelings, I think, so due regard…
