Allow importing/copying gradients between InDesign, Photoshop, and Illustrator.
It should be possible to import gradients swatches from Photoshop and Illustrator into InDesign, and vice versa. Whether by finally being able to have a gradient saved in CC Libraries or being able to copy+paste an object with the gradient applied between programs.
I can't tell you how many times I've finally gotten a perfect gradient in Photoshop, only to then realize I need it in InDesign and my only options are to 1) painstakingly make it again in InDesign, 2) design InDesign things in Photoshop with the existing gradient, or 3) Export a gradient from Photoshop as a jpeg and import that into InDesign to use in a clipping mask. This should be as simple as clicking Export/Import Swatch or copying and pasting an object from one program to another.
