When in magnified mode I experienced that it would be great to have the undo/redo buttons closer to my pen like the eraser/pen switch. Additionally I'd like to suggest further enhancements:
- seperate x2 and x4 buttons
- one defineable magnification button which remembers the last magnification through pressing it longer
- sometimes I do two column writing on a page. Therefore I position the magnification indicator rectangle manually at the desired position. Would be great if then the return button would position the rectangle one line lower but at the same column and doesn't move it back to the leftmost position. This by the way could be forced through longer pressing the return button.
