Loving the apps!
ICloud is great but i uses Onedrive myself mostly because you can chose where on your device that the files are stored (iCloud is ONLY the C drive). I would love if your wonderful team would consider adding separate storage locations such as the Onedrive, Dropbox, CC storage (I understand if you skip this one!) and Google Drive.
I have your windows suit of apps as well as the iPad designer and i would love to work on one file. currently i have to use the iCloud drive as a go-between to make the workflow viable but you allways end up with file blot when you pass them to a middle ground like this.
I did a quick search to see if this was already addressed and did not find anything. However I am new to this form so i apologize if I missed this from another user.
