3sided anki card

I you have any suggestions about the 3 sided anki card addon, please let me know.

Can you elaborate on what you mean by a “3 sided card”?

It is a bad card template; it causes an interference between the siblings.
Here is one of many posts on the interference: https://www.reddit.com/r/Anki/comments/5tas6x/interference.

Will 3 sided cards be possible in future versions of Anki?
