Synchronize PDFs in Saved Articles across devices.
I find selecting PDFs for later reading on an iPhone quite doable, but when I want to read them on the ipad or PC; I have to duplicate that chore. Ideally, Saved articles and later the Reading List on the PC would sync.

Sending PDFs between devices would violate the terms of service for most publisher licenses. However, with the release of My Articles coming soon, you will be able to sync the metadata for those articles giving you one-click access to download that article on any device. Thank you for the suggestion!
