Oh! OK 🙂
You can have up to 4 frames before and 4 frames after. See the columns in the screenshot above. You can drag those black parts up or down to increase or decrease the visibility of each of the backlit frames. If a column is all the way to the bottom, like +4/-4 in the above example, it will be turned off.
Does that answer your question?
