Saving settings for spaced repetition

When studying for an exam, I often want to use different spaced repetition settings depending on how far away the exam is.

It would be really nice to be able to save custom presets and switch between them easily. For example, I could have one preset for exams that are a few days away, another for a few weeks away, and so on.

That way I wouldn't have to manually change all the settings every time.

Keep up the good work, I really appreciate Flashka!
