After a while, our vaults will be filled with tens of thousands of notes, and there are more to come each day. These huge number of notes are impossible to process.
Suggested features include elementary one and advanced ones.
Elementary ones: auto attaching referenced sources(pdf, pics, graphs), adding tags, auto including relevant information, etc.
advanced ones: Auto-generating new information/content/ideas/connections based on current notes in the vault. This can be implemented by deploying machine learning methods, which was trained by existing books/courses/internet content.
