When switching into a Collapsed Graph, then backing out. It completely zooms out of the Blueprint Canvas. It would be nice if it could save your last position as it does when you switch between functions and other Blueprint Canvases.
I understand there is a new way to zoom in the upcoming 4.1 Update. It would be nice if we had the classic techniques of focusing on objects such as F focusing on Selected or a Selection of Objects. A zooming out and focusing on all the objects within the Blueprint Canvas.
