We would love to see a single view that shows a timeline with new deals, news notes, activities  etc.  The value of this view is catching up on things after time away. It should answer questions like:
- Have you seen this new deal
- Did you reply to ..
- Did you read the note on .. 
- Did you follow up on .. 

This view should make a coworker be able to catchup on things and get up to speed.
