EPIC Goal

Enhance the Developer Lightspeed user experience in RHDH by introducing chat history management, favourites grouping, and refined in-chat UX improvements. This will empower users to better organize, revisit, and interact with their past AI conversations while maintaining a clean, intuitive interface.

Why is this important?

Customers can easily rename, sort, and favourite key chats for quick reference, saving time when revisiting important AI-assisted conversations.

Enhance the Lightspeed chat experience to make it more intuitive, trustworthy, and maintainable by improving interaction flows, reducing visual clutter, and ensuring intelligent, context-aware behavior. This will increase user engagement, build confidence in the AI’s responses, and streamline the overall chat experience in alignment with Lightspeed’s core architecture (LCORE).

Acceptance Criteria 

1. 1. Chat History Management
      • Users can rename, favorite, or delete individual chat summaries via a kebab menu or right-click.
      • Renamed chats update instantly in the UI.
      • Favorite chats are grouped under a “Favorites” section at the top of the history panel.
      • Sorting controls allow ordering by name (A–Z, Z–A) or date (Newest–Oldest).
      • User’s sort preference persists across sessions.
   2. Chat Favorites Group
      • "Favorites" group is visible by default with at least one chat as a favorite.
      • “Always show Favorites group” toggle is available in User Settings → Developer Lightspeed configuration.
      • When the toggle is disabled, the group collapses or hides until expanded manually.
      • User’s favorite chat(s) should persist across sessions
   3. In-Chat UX
      • During AI processing, users see a subtle “Thinking…” indicator instead of verbose reasoning text.
      • Responses to general knowledge questions omit unnecessary RAG citation prompts.
      • Model selection is disabled for an active chat session.
      • Long responses render cleanly with proper indentation, bullet alignment, and visual hierarchy.
      • When a tool is called, Developer Lightspeed shows the trail of its usage: which tools are called, and from which MCP servers (currently just the built-in MCP server in RHDH)
