- Chat: added reusable snippets with `#` autocomplete in the composer and a Snippets settings page for global and project snippets with [opencode-snippets](https://github.com/JosXa/opencode-snippets) plugin compatibility.
- Multi-Run: runs can now be split into separate prompt/model groups, and Multi-Run prompts support command, file, agent, and snippet autocomplete (thanks to @tomzx).
### Improvements
- Desktop: Electron is now the desktop release target, with updated macOS menu actions for the right sidebar and terminal dock.
- UI: refreshed the desktop workspace shell with a full-width header, framed chat area, and smooth left/right sidebar open and close states.
- Chat: completed reasoning blocks stay collapsed without replaying the collapse animation when you reopen a session.
- Files: file search and mention results avoid mixing entries from similar query/cache keys (thanks to @isanchez404).
- VSCode: switching between chat sessions is less likely to stall on very large conversations.
- UI/Localization: refreshed Simplified Chinese terminology across the interface (thanks to @luojiyin).
### Fixes
- Voice: preview audio now stops and cleans up correctly when you stop playback or leave Voice settings (thanks to @isanchez404).
## VS Code
### New
- Sessions: opening a session now fetches a smaller initial message page, while still expanding enough to show the latest user turn when needed.
### Improvements
- Sessions: switching between chat sessions now keeps less inactive message history in the webview, especially after opening large conversations.
- Chat: task tool results use final task summaries when available instead of repeatedly loading child-session messages.
- Chat: task tool polling in the extension now uses smaller message fetches while subtasks are active or idle.
- Chat: markdown file links now cap path checks in the extension, reducing stalls in messages with many inline paths.
- Chat: the extension header reads only the active session title and latest usage data instead of reacting to the full session list.
