Dock able Modules in Outlook 2016
There is a usability issue due to the fact that you can only see one list at a time in Outlook, (email, contacts, to-do, calendar, etc.) There's the ability to "pop out" an email message so that you can look at your calendar while composing a message, but that's kind of clunky. I propose a feature where you can pop out any of the list modules (such as calendar) so that one can easily work between the two.
Adobe does this in their pro software by being able to "dock" windows within the interface window or "float" them elsewhere, including other screens. It would be nice to be able to float the email list on one screen and calendar on another - and have it remember the configuration on reload.
