One question though - have you ever tried connecting a Google, Dropbox or Adobe account? The experience is hugely different - with those providers the integration is tight, and simply by modifying a file and then closing the file, it automatically gets saved back to cloud storage. You don't have to "download a local copy" (though obviously it does in the background). That is what we are looking for, but with OneDrive. That is certainly for Adobe to develop, not Microsoft.
