Hi MEB, good you are looking ahead and are actively prioritising future features. Hear my voice in support of jcburns. Rolling out a professional grade app for the iPad, with cross-platform feature parity advertised but lacking direct access and seamless sharing to the Affinity Photo folder on iCloud is a severe let down. This is one of the gaps to be filled, urgently.
Were it not for the rich feature set already available on the iPad, "Black-box" storage would be a killer. "Black-box" storage on an iOS device is usually a reliable marker for crappy apps that will be deleted immediately.
Count my voice, I will bear with you.
