What are the best macro-areas for an Editing Tool Dashboard?

I am a designer, working on an editing tool. The tool will be an online platform used by a team of instructional designers to create presentations. You have an editor where you create the presentations and a dashboard where these are saved.

The designers need to: Quickly access what they are working on. Easily group similar presentations. Invite colleagues to work and review.

I wonder what are the clearest, most simple macro-areas to find on the dashboard to organize the files created. Any good examples? Thanks a lot
