In the wysiwyg editor, when you highlight some text you want to be a hyperlink and then click the link button, it shouldn't prompt you for the "Link Text". It should just use the highlighted text. This is similar to how it works in other common wysiwyg editors like Google Mail. Maybe also put both the "Link Text" and "Link URL" in the same modal to ease any confusion since it would be a change in UI behavior. Thanks!!
