Add lines, rectangles and Arrows, pen

[musthe]

It would be very useful to add the possibility to add lines, rectangles and arrows.
I'm using XnView to view my pictures and to import screenshots. On these screenshots I used to add comments and arrows on curve measurements.

Thank you.

Use the "Paint" plugin. It is integrated in the "full-downlaod-package", and you will find the command "Paint" in the "Filter" menu.
