Currently only way to import/export photos to cloud documents is via Save as dialog on desktop, or opening single photo on iPad.
It works fine if you have a single file that you work for weeks but doesn't work if you want to retouch 100+ photos.
1) Please make an option on desktop to just import a folder of photos to cloud documents so you can start to work with them on iPad.
2) Please make an option on desktop to export selected/all cloud documents to a local folder in selected format. Batch save as jpeg basically.
It should be quite simple to do but will make this whole feature usable for retouchers/photographers.
