Even though I have been using Photoshop for 14 years, I still qualify myself as an absolute newbie. So, when the right panel of controls has changed suddenly to something much less useful, I have absolutely no idea as to how to return it to its previous self. Also, now there is a floating pop-up that has a few elements that are now missing from the right control panel. I've circled in green the panels of which I speak. Now I can't do anything.
