Hello , thank you for your wonderful application.
I'm a Japanese and learning English words with this application.
I have some requests.
In View mode - Deck Statistics - by Percent,
would you subdivide each items(especially in high correct answer rate)?
When reviewing, I think 80% and 95% have different meanings.
I chose Random in Show Side First option.
When I swipe to right to undo and then come back,
sometimes(maybe in 50%) the other side of the card is displayed.
It's not a big problem, but I would like it if it would be fixed.
And I suggest that the sum of interval of all active cards
(or the sum of left time to become due) is displayed in some screen.
It would be an indicator of progress in a specific deck in Spaced Repetition.
