Dialog cards

Is there any documentation on the "repetition" mode for the dialog cards?

Is this based on a spaced repetition algorithm?

Also, what xAPI statements can these send?

Thanks!

When creating dialog cards, you can choose how you want the text to align, but when I view the text always aligns as 'center'.

Hello,

I would like to see an feature in Dialog cards where you can add different image on opposite sides of the same card.
