You're right, currently Ferrite leans developer/tech with Mermaid, JSON/YAML tree viewer, and CLI integration. The Obsidian-style features (wikilinks, backlinks, knowledge graph) are coming in v0.3.0.
Target audience is probably "developers who take notes" rather than pure writers. The native performance angle is the differentiator, same niche as "I want Notion but faster" or "Obsidian but lighter."
