For images, I usually use Preview to add shape annotations (like lines, rectangles, ovals). There, I can change/edit attributes of the shape like line color, line width, and fill color.
In DT4, while I can add these same shapes using the annotations in the editing bar, the only editing controls seem to be those available by right-clicking, then selecting “Edit…”, which seem to allow adjustments to the entire image but not to the shape annotations I just added. Is there a way to edit just the annotation shapes?
