Is your feature request related to a problem? Please describe.
I find the ilvl text hard to read sometimes depending on the icon, especially if the option to colour the text based on the item quality is on.

Describe the solution you'd like
Add an option for text shadow/outlining or maybe a shaded background of some kind.

Describe alternatives you've considered
Make the item quality a coloured border instead of/in addition to colouring the ilvl text.

I am a bit confused, I came here looking for answers because I have a similar problem.
I wish colored borders would be a thing. In screenshots of Bagnator on curseforge they are allready there?
Do I miss something here?

To add to the wishlist, make it an option to brighten the colours of the border.
The addon "Bagnon ItemLevel" did something similar for bagnon, it is super nice.

I'd really liked this being implemented

I've experimented with different options, and there isn't a good solution for the ilvl text, and adding a background looks odd.

The item buttons should already have coloured borders representing their quality. If they don't its probably a Masque skin issue.
