I like number three. Any visual way to represent and control exposure is a good call imo.

Hi. I wrote some suggestions for your consideration in an Abyss task: T6122
I was told most of those suggestions have already been discussed. Other suggestions include being able to quickly change the Start and End frames by dragging brackets on the timeline, and also being able to change the past and future onion skin length by dragging other brackets.

Hi @Bollebib, thank you for reviewing this.
