The integration of Stock and Photoshop is much improved in the latest version, but there's one thing that's missing.
I often download preview images to see if they'll work in my projects, but there have been a few times when I've forgotten to license stock images before exporting the final graphic. (Sometimes the watermark is hidden behind my other graphics.) I've gone back to license the images once I've noticed the problem, but I'll certainly miss one eventually, if I haven't already.
Could you add a reminder in Photoshop to license any unlicensed stock images before exporting?
