I often zoom into a mockup to work on some details. Sometime I obviously will have to pan the work area to access elements in the lower right parts of the mockup. When I use CTRL+1 to go back to the 100 % view, the panning is not restored to the original view, which means I only see a tiny part of my mockup. As there is no shortcut to pan to the top left (like “home”), I have to do it with the mouse using two scrollbars (or slowly panning with the keyboard shortcuts). Another workaround is first go to zoom to fit with CTRL+0 and then to 100 %, in that case the panning is restored correctly.
