During everyday use of Revizto I need to review issues that have been tagged and check to see if they are still relevant, while doing this I need to continually flip between the mark up views and the model 3D view. 

While keeping the 3d view open while I go through the issues has served as the best solution currently, the photos in the chat section are too small to really review things properly. 

The feature I am requesting would be the ability to split the mark up and 3d views into separate view boxes which would allow me the ability to see both of these views at the same time to more quickly see if the issue has been resolved.
While I know this isn't applicable to everyone, I do work with multiple screens on my desk and the additional ability to use a second screen to do this would also be very much appreciated.
