Absolutely. Right now Planner is very limited as an enterprise solution. Every plan/project is in its own silo and one can't manage resources, tasks or projects outside of a small team. The following features are critical before we can deploy across our organization:

• Resource management across multiple projects. As a minimum it should be possible to view the Assignments and Charts tabs across a whole group, not just a single plan. Similar for People and Goals tabs would also be useful.
• Task dependencies between different projects
• Task requests into a project, allowing outside the project team to make a request that the Project  Manager needs to accept
• Allowing a task to be in more than one project (could be similar to the above)

Other items that would be helpful:

• "Sticky" views, with the current state of filters, group by, zoom, date range etc retained between sessions
• Bulk update of tasks
• Moving tasks between projects
• Keeping effort constant when duration of a task is changed
• Allowing top-level tasks to connect to Goals
