Note-Decay
I kept forgetting to revisit my old notes, so I built this plugin that makes my neglect visible.
Note Decay weighs decisions for each note with a little Again/Hard/Good/Easy bar (SM-2 algorithim, same idea as Anki) and then color-codes your whole vault by how close each note is to its next review, creating an informative heat-map:
freshly reviewed
starting to fade
almost due
due / overdue
Grading system:
Its ultimately up to the user how they decide to review the notes, and by which metric they decide the difficulty of this recall. This is only a data visualization tool, flashcard generation or study methods are not provided.
When using the plugin on existing vaults, un-graded notes are seeded from their file’s last-modification date.

I would really like to get some feedback to see if this tool helps anyone improve their study habits using this tool.
