Scrubbing the timeline : actual view ?
I think it would be great if you could scrub the timeline in Storyline.
Being used to Flash, I find having all object at once confusing (and actually I don't see the point apart from a visual mess).
The problem is you can't see what you actullay get under playhead unless you play your scene.
Could you consider having a mode where you only see on stage what's under the playhead ? I recently had a busy timeline with many speech bubbles and I spend my time hiding/unhiding layer to get everything in place.
What do you think ?
