I tried searching the forums with no success. Does Duolingo have flash card capabilities coming in the future for Dutch? I feel it would be extremely helpful. Yes, I know I could make my own but that would defeat the purpose of convenience that this site brings!
I assume that since they are developing and testing the flash card feature the goal is the implement it in all courses. I however have no details on this so I might be wrong. Also since they are still testing it now it may take a while before it is implemented in the different courses.
