I would very much welcome an alternative option to navigate the Flow view - clicking / pressing middle mouse button to pan the view, e.g. as in web browsers. This pan should virtually move the camera as opposed to the current RMB virtually moving the content, if you know what I mean... Simply put if I would want to see a content that is below the bottom of current view, I would hold the MMB and move it downwards (with the current RMB style I have to move it upwards).
This is a matter of preference for sure, so I'm not saying you should replace the current method, but putting in this alternative as an option would be great
