i wanted to suggest a new feature or a wanted feature that isn't in the program yet.
that you can control the background and foreground options.
How i think it would work:
My dear would be to leave the timeline as it is and many add a button so another line comes were you can control the back and foreground.
Also so the tables are clear many make it so it is already copped from the original one so the users wouldn't get confused.
Thanks for reading
