Adobe has crammed more features into Photoshop on the desktop than most people will ever use, but you can make use of at least one of the features you're (probably) overlooking with Pixl Preview. This app plugs into Photoshop's remote connection system to act as a second-screen preview of your designs.
Requiring a live preview of what you are working on in Photoshop, is a need. So with Pixl Preview working as a plug in, the term don't panic comes to mind but used fairly well. Added to the menu, Preview helps you achieve a clear desire to preview images just as we have always wanted to.
