I love the idea of combining an outliner and an SRS. I don't love the idea of needing a new special editor for them, and a new siloed data store for them.
Now, if this were an SRS that read my existing data (like from Notes.app, org-mode, OmniOutliner, or Excel) and presented it as an SRS, that would be very cool.
