Message:
add a navigation bar This adds a simple navigation bar since web browser are apparently dumbler than most Gemini browsers. The "Root" link points to the capsule' root, "Home" to the current home directory and "Up" to the parent directory. Users home are discovered using a simple heuristics: ~user path components.
