setting the duration of a scene (where possible)
Very simple - let the user set the accurate duration time (in seconds) when it's possible.
For example, if I have a simple scene where there is only a background image and no elements at all in it.
In such a case, I would like to have the capability to define this scene's duration time.
I know there is an option to drag the edge of a scene in the timeline editor, but that rarely works, and anyway that's not the official way to do that (and it wouldn't be accurate).
