In Composer 2014 you could pan your paper space around the screen by holding ctrl and pressing center mouse button for pan mode. It seems like in 2016 this feature has been removed or I don't have a setting set correctly. In 2016 now it seems the center mouse button is rotate not pan and holding ctrl changes it to pan mode effecting the model only. This is a fairly important option as I design very large posters that require zooming in and panning to the correct spot in paper space to add notations, details views, etc. Does anyone know if this in fact has been removed or of a setting I need to check.
