- Displaying the original webpage's URL at the top right is very much like the web browser's address bar, which may confuse the user about her current location and create an illusion that she is actually on the original webpage. If the user follows a link on the original page, either because she thinks that the new page will also open in WebAnnotator or by accident, she will be redirected to the new page, exiting WebAnnotator, which may be unexpected and risks the user to lose her work on WebAnnotator if it is not saved. A prompt on redirection asking for confirmation ('By clicking on a link you are about to leave WebAnnotator. Do you want to continue?') may help.
