We have been doing a lot of training on Planner and OneNote recently and had an idea born out of some user frustration. Currently, there are several places that you can create/track tasks and projects that you work on. Thinking along the GTD methodology, it would be great to have a personal HUB in Office 365 that presented you will all of the tasks created/assigned to you across the platform--Outlook, OneNote, Planner, SharePoint. It would be further fabulous if those tasks shared a similar tagging structure.
