Adaptive Tasks - Spaced Repetition

[plc-dev]

Use the gathered data and statistics to implement a system that adapts the task difficulty and tips/help according to the users familiarity/expertise of the task. Combine this with a [spaced repetition](https://de.wikipedia.org/wiki/Spaced_repetition#:~:text=Spaced%20repetition%20(%E2%80%9Everteilte%20Wiederholung%E2%80%9C,der%20Wiederholung%20gelernter%20Inhalte%20vorsieht.) algorithm that reminds a user of when to practice a task again, to reach the "optimal" repetition rate in order to maximize retention.

• Adaptive system according to user statistics
• Spaced repetition algorithm
• Push notifications/server sent events to remind a user of when to practice a task
