Is there any way or a good solution to define custom icons and colors in callouts themselves? And with little or no CSS?

@CawlinTeffid It’s been three days now, can yo unlisted the feature request now? Allow defining custom icons and colors directly on the callouts themselves and without CSS

By the way, where does it go when unlisted? Are posts in categories in chronological order and the FR would be in the area where others made a few days are?
