I had a look at the new flashcard system and it looks quite powerful but for me it's not intuitive enough to start without some additional help.
For example this group of buttons:
- The text "Begin Study" is vertically centered to the whole button group, so it looks like this is the main button and the two buttons at the bottom are a kind of sub-button. If this is not the case I would suggest to use a horizontal arrangement of the icon and the text, like for the bottom buttons.
- I can guess what "Promote to Review" does, but I am not sure about "Mark Completed". I am also not sure why they use different colors...
- I don't know what pressing "Begin Study" actually does, compared to the other two buttons
