Ive been hard pressed to find a program for iOS and more specifically iPad Pro that has the ability to open and edit PSDs while maintaining the integrity of the layers that already exist. This program does that well at its most basic level, but some important features are being overlooked. I was very excited to see that Dropbox integration was released recently, as all my files are stored there, and not having to import via my laptop to then edit on the iPad would be a huge time saver. What Ive found is that some file formats (.png) import with little difficulty, but .psd files give a Dropbox error when trying to import directly from Dropbox on the iPad. The integration is useless without this feature working. Layer masking is missing from the desktop and mobile versions of this program as well, and thats a near deal-breaker for me. But with my other options not including these features either, I dont have much choice but to struggle through without it. This program would be an easy 5 stars from me if these enhancements were added.
