Now that you have submitted some jobs, you will want to monitor them in the Qube UI. In fact, there are now two Qube UIs - the original, now called Wrangler View (because it contains features that an administrator or render wrangler would use) and qubeArtistView, intended for artists to monitor and interact with their jobs.
If you have been working through the Qube 101 documentation in order, you will probably be running the Wrangler View, which has a white background and an "Administration" menu item across the top. In this section we are going to skim across the surface of the qubeArtistView UI, but most of the things covered here will also be true in the Wrangler View, though you may have to look in slightly different spots to locate them.
To launch the Artist View, do this:
Windows: Click on the black and white Qube ArtistView desktop icon, or locate it in the Program Files\pfx\qube\bin folder (Note: not the "Program Files (x86)" folder)
OS X: Click on the black and white Qube ArtistView desktop icon, or locate it in the Applications/pfx folder
Linux: Type 'qubeArtistView' at the shell prompt (no quotes)
