This is the Zoom I have been waiting for, so simple to use and works extremely well. Thank You Konrad.

Suggestion: When zooming, make the mouse pointer the center of the expansion (like in Windows Photo Viewer). Right now, the center of the expansion is fixed in the center of the image. This addon is not just cool, it also helps people with eyesight problems. Aslo, in the description of the addon add information about where suggestions should be sent.
