Positives

After waiting for an app like this, I'm thrilled with Hubble! It checks almost all my Markdown editor wishlist items, and I even customized it with Claude Code in no time.
The tree file view is reminiscent of Obsidian, making it easy for users to navigate their notes, which could boost productivity significantly.

Concerns

Why choose Node.js for this app when Rust could offer better performance, especially with LLMs enhancing productivity?
