I think Inkdrop is excellent for storing, organizing, and filtering information, especially technical stuff. But that is also its limitation.
The quantity of information stored would increase substantially with time, and we would likely forget much of it without active recall and review.
Other note-taking apps have already implemented evidence-based remembering techniques like spaced repetition, namely RemNote and Notion. I think Inkdrop should do the same. This lack of features is one of the things that prevents me from switching entirely to Inkdrop.
My recommended feature: randomly pick up highlights from the notes along with their context and show them in notifications/emails at predefined intervals (daily/weekly/monthly/etc).
+ Inkdrop is already available on multi-platforms, and is mark-down based, so adding supports for highlights should be easy.
+ The highlights can be picked up randomly, or based on the user’s preferences (e.g. pick up highlights from the notes that are tagged with “important”).
