Apple should have made an iCloud Drive app like Dropbox. It is so fiddly still to view documents in their sandboxed apps still. Several of my apps have been updated to support the new iOS 8 document picker but the document picker does not allow you to delete or rename documents. One of my apps allows me to import documents into the iCloud Drive. Problem is once they have been imported I cant edit their names or delete the files. I guess Ill just have to do that on Yosemite but that kinda means you have to use a Mac or PC in order to organise your files. Its crazy!
