User can flag cards for editing during memorization and can open a list of flagged cards at a later time.

I'd like to be able to mark a flash card for later editing while I'm in the middle of memorizing. I'd also like to be able to pull up all marked flash cards so I can edit them. The motivation for me was this. I imported flash cards someone gave me, and for several of them I knew the answers were incorrect but didn't know the right answers. It wasn't convenient to do research at the time (the information isn't online or easily accessible) and I wanted to continue memorizing. I also didn't want to continue seeing the false cards or rate them incorrectly.
