Although the new app has the slight advantage of allowing random access to the articles so that you can go directly to a topic of interest, it has several drawbacks. On the IPad it will only display in portrait mode. My IPad Pro will only stand on its keyboard/cover in landscape mode so that makes it harder to use. I also miss the intro and the current organization is not chronological.
Also, there is no vocabulary page or list idioms.
These problem could be easily fixed (since the content exists and almost all IPad apps switch modes).
Two things I would like to see added are the ability to create a list of words and definitions to study later, and the ability to look up any word in a French-English dictionary. The highlighted phrases and translations are helpful, especially for idioms, but I often come across other words/phrases I need translated. When reading French text on my Kindle I can highlight any group of words and get a translation to English. That would be very helpful here.
As a developer myself, I don’t think it would be hard to make these improvements and then this App would be better than the older version.
