Theme customization

[SealDev]

How could I darken the background color of the dialogue window grid, or even remove the grid altogether in case it's an image file?

I would love to set a fully black color background.

(Some editor theme customizations can be done in unity since recent versions using StyleSheets .uss files. I made most of my editor black)

I'll consider theme customization when we move the Dialogue Editor from IMGUI to UITK. The Dialogue System currently provides several ways to customize the Dialogue Editor, but it doesn't include changing the background but rather things that are of a more substantive nature such as showing extra info.
