v1.5 has just been uploaded for review ready for sale next week. A quick lowdown:

✩ Quizlet support - search millions of decks on www.quizlet.com
✩ Touch the colour piles on the study screen to show their contents
✩ SRS interval adjustment in settings (advanced users only!)
✩ Minor changes

Due to changes in the Flashcard Exchange API, "tags" are no longer available when searching.
