I know people have asked before for the ability to link notes together, but I believe that there is a valid use case that has not been considered in the replies that I saw.
What I would like is the ability to link notes by a common key, and then for the scheduler to treat all notes linked by the same key as if they were one note.
The reason for this relates to language learning where often you have different grammatical forms, but each form is based on a word base. For instance, an example in English would be:
- to clean (verb)
- cleanliness (noun)
- cleanly (adverb)
It is useful to be able to learn different grammatical forms, but as they have the same word base it is better to not schedule them as new cards on the same day.
It is not feasible to have a note type covering all grammatical forms (that could end up with hundreds of fields and card types), hence the desire to have note types focused on each grammatical form, but linked for scheduling by the word base.
