The Spaced Everything plugin brings spaced repetition to your entire vault by helping you revisit and improve your writing over time using the SuperMemo-2.0 algorithm. Notes can be onboarded into a spaced writing practice (SWP) queue, where they are reviewed based on prior feedback like 'Fruitful' or 'Unfruitful'. You can create separate review contexts (like work or personal) and even customize the review logic using your own JavaScript-based spacing algorithms. The plugin also supports quick capture of fleeting thoughts, toggling context membership, and logging review activity in JSONL format for further analysis.
