Incorporate Middle Mouse Button to eliminate SELECT ZOOM LEVEL & HORIZONTAL AND VERTICAL SCROLL BARS

Program Window update to incorporate "middle mouse button" functionality in the Program window. Giving the editor the ability reposition and select zoom level (like in After Effects, Photoshop, Illustrator, etc.). This would save editors an eternity of time. 

This would elimainate the need to use the "Select Zoom Level" drop down box, as well as eliminate the use for the vertical and horizontal scroll bars.

IE: Click and hold middle mouse button to reposition the "camera" (for lack of a better word) in the Program window. 

IE: Allow us to create a shortcut with the incorporation of the middle mouse button.
"Zoom Monitor In" - (CTRL + Scroll up)
"Zoom Monitor Out" - (CTRL + Scroll down)

Editors currently have the shortcut of "Num+" and "Num-" to Zoom Monitor In or Out, but an option where our right hand would not have to leave our mouse, would be much more proficient.
