I've long wished for some of the functionality of Adobe Capture to be accesable to Photoshop without having to export an image as a Graphic, and then work on it with Capture on my phone. Wish has been granted! In the Libraries panel, if you click on the Add Content icon, one of the options is "Create from Image". This opens up Capture right inside Photoshop.
I'v liked Cature for its pattern making function, but a cool new feature is to make gradients from your image. You can drag the stops around, sop the gradient will be sampled along a path (not an actual Photoshop path, though). I can think of a lot of uses for this.
