Not that I'm going to buy a reMarkable, but I do wonder what kind of organization tools it provides. Being able to tag a given note with arbitrary categories and have the device produce a date-ordered index on any category seems like it would help with this a lot.

(I use a similar system in my paper notes, with a topic index mapping to page numbers. A few minutes of grooming a day suffices to keep it up to date, and it speeds lookups enormously.)
