v2.8 has just been uploaded for review ready for sale next week. A quick lowdown:
✩ Touch the colour piles in the study view to see their contents
✩ Dictionary lookups are automatically stored in a new deck called "Dictionary History"
✩ The study algorithm's spacing (SRS) can be changed, if so desired, in settings
✩ New option in list view shows "Last asked" for each sticky
✩ Background dictionaries have been speeded up - a little faster on older devices
✩ Slight blurriness in tile view when zooming in using the pinch gesture
✩ Other minor bugs
