Are there plans to provide iCloud support? Not a critical thing (as I use Dropbox) but if you were looking to add Google Drive it may be a simple extension to add this as well?
Thanks for your inputs, they are quite timely.
iCloud can mean several different things but I'm assuming you mean iCloud drive here as a Dropbox alternative.
Initially in Foliobook 4 we believe can support single image imports from a variety of cloud services where the provider of that service has created the appropriate hooks. This will be on iPad Air 2 and iPad Pro, not sure about older iPads yet.
Later we'd like to support multiple downloads from iCloud drive, but after the new UX changes that you have referred to.
