Problem case

Is your feature request related to a problem? If so, please describe it here. E.g.: "My workflow is such and such, and this and that would help."

There currently exists a large unmet need for those who could benefit from a tool like this to help them memorize content that is much larger than the 20 items provided by default.

Examples include:
Poetry
Song Lyrics
Speeches
etc.

Solution

Concisely describe the solution you would like

2 ideas for how this tool might be expanded to meet that need include:
1: Linked Lists
2: Drill Down Lists (i.e. "Trees")

For a Linked List, the user might want a list of >20 items to be broken up into smaller lists, each of which contains <20 items.
Once generated, the "list of lists" might look like the attached image.

The Drill Down List is the same idea, but it also offers a single top-level list where each of the sublists can be given a more meaningful name.

Concisely describe alternatives you've considered (if any)
