I keep multiple tabs of Bridge open at once when I'm authoring courses.
- One tab has the course in preview mode
- Another tab has the course in edit mode
- A third tab is for pulling in content from other courses or adjusting settings
It is easy to go from edit to preview mode. It is less obvious how to go from preview to edit mode. More importantly, it is hard to open edit mode or preview mode in a new tab. See screen shots below:
