Description
Hi! I just made an obsdian alternative in terminal after searching for an Obsidian like TUI and got nothing. So I built one myself.

Could you build this?
Partial While an AI can generate basic Rust terminal boilerplate, implementing a high-performance, robust, cross-platform TUI note-taking app with markdown rendering and bidirectional linking requires idiomatic Rust systems programming.
What it would actually take: The architecture relies on Rust using terminal libraries like `ratatui` or `crossterm`, backed by a custom markdown parser (e.g., `pulldown-cmark`) and an in-memory graph index for bidirectional wikilinks. It requires expertise in low-level memory management, terminal event loops, async file I/O, and efficient index synchronization.
