Highlighting substitutions

Hi. I hope you will add some color variations to substitutions of drawing. It feels like my eyes will explode after working on my 17" laptop tying to animate with substitutions. Thank you

Please explain more because I don’t understand your request.

Thank you for response.
See picture attached


I mean it is hard to see substitutions on a timeline if i changed it once or twice, for example. Especially if scene length is big

Yes , that would be great if you could such a feature.

Have you tried this script
