Delete existing cards

I created my own spelling deck, but I recently joined a course and want to add new words and remove old ones. Currently, I have to learn existing words first. It would be great to have buttons to add and remove words directly.

Hello, can you please explain the suggested feature in more detail? Currently, it is not clear what you would like to suggest. You can create a new language desk. Learned cards don´t stop you from adding new ones.
