After considering all options, we’ve decided to discontinue development of our plugins. Much better apps than Photoshop are now available for designing, and many people have already moved on. Additionally, the Photoshop API is very limited and extremely hard to work with.
We will continue our mission to help people work faster and better, by building useful and time-saving macOS applications like PixelSnap or CleanShot. We hope you’ll join us on this new journey and try them.
