- Slash commands (/code, /nostr, /design, /search) now appear in the prompt palette with descriptions, auto-send on select - Chat message hover actions wrapped in a proper glass container with backdrop blur, divider between actions and feedback thumbs - Palette has 8px side margins, no scroll limit - Fix app extraction: queries mentioning known app names (e.g. "start9") now surface the Apps tab even without explicit app/nostr query patterns Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
