An application development team has recently requested to overload the standard open in new window link with a dual purpose set. I.E the regular text link as mocked up below would open the link page in the existing browser window, but if the user clicks the new window icon the link page will be open in a new window/tab. This seems like a dark/anti-pattern but then again how many user really know they can right click and open a link in a new window.
So should this type of functionality be supported?; or is it better to give these internal users training and have them right-click to open a page in a new window as they need it.
