Hopefully this is an easy one and something that I'd imagine other developers using the VS extension would find useful.
There is lots of output going to the AppBuilder output window on build, but the final URL is not shown. While I can capture and/or copy it from the build output window - if I close this window - to say debug or review code - which is required because it's a modal - I then have to rebuild again to get the link - rather than just go grab it to include in emails to share with clients or for testers. I frequently find that I'm rebuilding just to get an install link for a build I already had.
This would also support running the build in the background - which would be a huge time saver. Currently I have to sit and do nothing for 30 secs while the build runs and VS is inaccessble. If the URL showed post build in the output, I could start the build, move on to do other things, and use the URL when its done.
