Feature request: 'Fade out Excalidraw Markup' select the font colour

[brianarrison]

Hi Zsolt,

I like the 'Fade out Excalidraw Markup' feature but worry that because it fades out to be almost invisible, I might accidentally delete some of the markdown. ( Ideally I'd also like to have the markdown below %% in a coloured box like a callout)

So, could you add an option to select the font style for the faded out area, or is there some css that I can use to do that?

thanks

Brian
