Idea - I would request a 1/2 indicator for the zoom to sequence function. I get sick of editing and losing my zoom to sequence in/out positions. If the positions were static - unless you adjust them, it would be much easier to zoom out to user selected "zoom out view" and switch back to a user selected "zoom in view." It could be a small magnifying glass with a 1 or 2 in it or different colors. Both positions 1&2 would be adjustable - and they would stick with the user like custom keyboard shortcuts.
