The old version?
1) The simplicity
2) The possibility to delete from the email/archive/etc. button (the swipe-delete is not a sure-fire way of deleting articles and the edit button is just a few taps too many)
3) No useless texts with useless explanations when a folder is without articles
4) When you start up the old version, it goes directly to the list of articles if you left off there; the new version to the folders (which I don't use)
5) The graphical view now shows a lot of clutter (mostly links) on the page, not simply the text and pics (takes quite some swipes to scroll down to the text)
6) When exiting an article, half the time the article is not highlighted. So I have no idea what to delete and have to go back into the article which I think it was to make certain that was the one I can safely delete
7) ... and there are some headlines missing of articles from a magazine I've been reading since the App Store opened.
And then the non-responding of the writer of the app to my polite email is the last straw, really.
