HTML URLS should become links that open in a new tab. Right-clicking a link should provide an option to open the page in the markup view if it is an html document. JS If the .js file is available in the debugger then it should open there. If the link ends with a number e.g. some/url/somefile.js:65 then it should open with the cursor at that line. If the file is not available in the debugger then it should open in a new tab. CSS If the .css file is available in the style editor then it should open there. If the link ends with a number e.g. some/url/somefile.css:65 then it should open with the cursor at that line. If the file is not available in the style editor then it should open in a new tab.
