# Version 0.1.0

This is the initial release of Canvas Chat, a visual non-linear chat interface where conversations are nodes on an infinite canvas, allowing branching, merging, and exploration of topics as a directed acyclic graph (DAG).

## Core Features

- **Infinite Canvas**: Pan and zoom interface with native trackpad/touch gesture support for navigating conversations
- **Node-based Conversations**: Chat messages rendered as draggable, resizable nodes with support for branching and merging
- **Multi-model Support**: Works with OpenAI, Anthropic Claude, Google, Groq, GitHub Copilot, and local Ollama models
- **Session Management**: Create, save, and switch between multiple canvas sessions

## Canvas & Navigation

- Add semantic zoom with auto-generated summaries for nodes when zoomed out (5531ab0, Eric Ma)
- Add BM25 keyword search for nodes with Cmd/Ctrl+K shortcut (7e07769, Eric Ma)
- Add smooth animated transitions for auto-layout and pan operations (2b370f4, c5883a9, Eric Ma)
- Add one-click node resize to 80% viewport with scrollable content (84e86ea, Eric Ma)
- Add subtle fade effect on non-selected nodes to focus attention (61cd855, Eric Ma)
- Improve node fading: ancestors less faded than non-ancestors (2202429, Eric Ma)
- Make selected nodes more visually obvious with dashed outline (76046c9, Eric Ma)

## AI & LLM Features

## Matrix Evaluation

- Add /matrix command for cross-product evaluation tables (8efe873, Eric Ma)
- Support single-node /matrix command with two-list extraction (482e137, Eric Ma)
