I have just created around 15 flashcards. After creating, them I started practicing them.
I do not understand why 70% of them were presented to me as “Term :: Definition” and 30% as “Definition :: Term”.
I found this behaviour weird. Even if it is made on purpose. Whatever the purpose might be.
Just hope it is not a bug. Therefore, I am reporting here 
It’s not a bug. I was confused about this at first since it was not touched on in the tutorial.
I didn’t specify a type of card at all.
Apparently, the “forward and backward” option is selected by default.
Just found it a little bit confusing. No big deal.
Thanks for the reminder @TaQuangKhoi !
If you make Front a question, it will automatically be Forward flashcard.
Now the UI has been redesigned, do you know where I can set this feature? Thank you!.
For basic front only, use >>. For concept front only :>. Descriptors are by default front only, the delimeter is ;;.
Thank you! @UMNiK
The Youtube video about the latest RemNote version also helps answering this very question.
