I'd love to see 21 have the ability to have multiple windows/screens open at once instead of me having to have multiple instances of the game open so I can look at stats, rosters, etc. while setting my depth charts, play packages, etc.

This will be looked at on a case by case basis. In theory we can make some of the popups resizable and movable, or add additional popups so you don't have to leave the screen. We also have more screen space to add additional data when beneficial.
