Ability to divide the panes vertically
As in VS WPF design.code window panes, I really like to have the ability to create vertical panes for coding and results whenever I want. Like to press some button and change their orientation from Horizontal to vertical or vice versa.
It's unlikely that this feature will be implemented; however you can now press F8 and undock the results window into a second monitor.

In a wide screen, this would be very useful. Or we can combine this feature with the ability to view this pane in a separate screen.
