"User Landing Page" that would contain high level info relevant to the user:
i.e.
  • Quick overview of open assigned tasks / sub-tasks / comments / reminders --> with links to filtered results that would list the above at detailed level
  • info about upcoming milestones
  • conversations snippet view
  • view of most recent notes / docs / drafts --> with links to those notes / docs
  • weekly calendar view
  • recent activity overview - while you were gone section
  • bookmarks
  • etc...
Not sure what the plan for dashboards is, but if they prove to be flexible and if the custom filters could be placed on them, then the above could be accomplished with dashboard.
