Some difficulties trying to operate the tool

Having had occasion to experiment a little with this tool, I'd like to come back with a little more feedback:

• The way most users who are interested in certain details of a manuscript (letters, abbreviations, initials, passages of text, drawings, etc.) tend to work is that they zoom in first and when the item of interest is within view, activate the image cropper. However, what I often experienced at that zoom level is that the tool is then difficult or even impossible to use. It may cover the entire canvas or it becomes difficult to drag and resize. What I like about similar tools is that they allow you to zoom in and draw a shape, typically a rectangle, around any item of interest. Could that sort of functionality be implemented here?

• In some cases the tool would not appear to become active after clicking the icon in the menu. However, when I flipped back and forth through the pages, it turned out that the cropper region had actually become active, just on the wrong page.
