Flashcard Pet Peeve

I don't know if anyone has experienced this, but when i go through my flashcard deck and swipe to get to the next card it can sometimes take you back to the main menu. It is the most irritating design flaw, so if you've just reviewed 100 characters, and you get taken back to the main flashcard category menu, you have to swipe through 100 cards to to get back to where you left off. 

I once swiped to card 99 and it returned back to the main flashcard menu. Irritating!

Get rid of this annoying feature and replace it with a back to main menu button.
