Add some kind of logbook/navigation protocol?
Making the last 20 (?) steps available somewhere could speed up the navigation between the items.
What I mean is a chronological ordered list (with clickable items) like this:
- 'timeline titel 1': edit
- 'timeline titel abc': live annotate
- 'timeline titel abc': timeline viewer
- 'video title abc'
- 'video test title': edit _ ...
The user has the possibility to jump between the last visited pages/items/screens and doesn't need to navigate through the whole system if he want to make a quick edit of the video visited 5 steps back...
