Sometimes, when I'm editing a website using software not from Adobe (say WordPress), I want to be able to adjust a color using a color I've saved in one of my a color libraries. If I don't have Illustrator or Photoshop already open, it would be MUCH faster and easier to just open the CC Desktop App, select my library and see the hex values for my colors there. Right now, there only way I can use the CC Desktop App view is if the software I'm using has an eyedropper tool (which WordPress does not).
