Console output viewer for Office.js add-ins
Although you can see JavaScript console output in Visual Studio if you run the Office.js add-in from VS, there is apparently no way to see this output when running outside of VS. Since Excel is the host of IE used to render the Office.js addin, perhaps these teams could collaborate to provide a console output viewer in Excel. This feature would greatly ease development and debugging.

Some sort of console output viewer is essential to any kind of web development, especially when there is a lot of javascript involved.
Vorlon and f12 sort of kind of work, but they are a bit of a fiddle, and dont catch fatal errors (bugs that kill an app), and therefore can't be used to fix the worst bugs.
Ideally all Add-ins should run in edge, and the developer should have access to the developer console.

Thanks, Sameera. However, at first glance, I see that Vorlon needs some non-trivial setup as well as a change to the target add-in. This seems fairly intrusive. So, I still hope to see the suggestion above implemented at some point.

If console output is what you are after, you can use Vorlon.js as described at https://github.com/OfficeDev/office-js-docs/blob/master/docs/testing/debug-office-add-ins-on-ipad-and-mac.md
