I use iCloud Drive at www.icloud.com
to store pdf files. I would like to be able to view and edit these pdf files the same way you can view and edit "Pages" documents using the Pages app. Is this possible? At this point, If I double-click one of the pdf files, all it will do is download, which I don't want to do. I like Apple. But, it seems there are too many limitations using the web interface.
