Allow apps to natively integrate alternative cloud services like Google Drive or DropBox. So many apps sync directly to iCloud, but have no way of natively changing that default sync location. Ran into this issue a while ago, where my work uses iPads in the field, but they can’t sync anything with each other because my employer has fully committed to the Google ecosystem. So I can’t just grab any iPad off of the charging rack and continue where I left off; I need to grab the specific iPad that I was using last time.
