It would be a huge upgrade to the entire Descript experience (and probably kill a lot of minor QoL feature requests) if we could customize keyboard shortcuts and mouse behavior to suit how we'd like the app to operate.
As an example, I've heard in office hours that scrolling the mouse wheel on the timeline without holding Crtl or Shift doesn't do anything because people found it confusing in the past. Why not just let us decide for ourselves?
