Feature Request: Add a comprehensive report generation feature to Recall that creates structured, long-form documents from filtered knowledge base subsets. The current AI chat functionality limits output to approximately 7000 characters including references, yielding only 500 words of actual content, which is insufficient for professional use cases. The requested feature should enable users to generate markdown-formatted reports of configurable length specified by page count or word target, similar to NotebookLM's report function. Users should be able to filter source material through tags or prompts, with the system proposing document structure and synthesizing information across multiple stored resources. The generated reports should serve as fact-based foundations for slide decks, customer presentations, or essays, maintaining proper source citations while delivering substantially more content than current chat outputs. Implementation should appear as a dedicated option in the sidebar alongside existing Chat, Graph, Review, and Settings functions, providing direct access to this document generation capability without relying on chat interface limitations.
