title: Oracle SQL Developer and code/line change indicator
body: <p>Does Oracle SQL Developer 4.1 provide an indicator for what lines were changed in the code editor? For example, in SSMS a <a href="https://stackoverflow.com/questions/13055378/what-do-the-different-colored-bars-in-the-query-editor-menu-mean-in-ssms">yellow vertical bar</a> appears next to the line number, whenever new code is added/modified/deleted. This line changes to green after it is saved.</p>
