Add Side Bar (Webview View) Support for Claude Code

Problem Statement

Summary
Requesting support for rendering Claude Code as a VS Code Side Bar view instead of (or in addition to) the current editor tab–based webview.

Problem Statement
Currently, Claude Code opens as a standard editor tab (webview panel), which competes with source files and disrupts the primary editing workflow. Competing AI extensions (e.g., Codex, Copilot Chat) expose their UI as a Side Bar view, allowing persistent access without consuming editor real estate.

VS Code does not allow users to re-dock editor webviews into the Side Bar, so this limitation cannot be addressed via configuration or user settings.

Proposed Solution

Proposed Enhancement
Implement a Side Bar view using viewsContainers + webviewViewProvider, enabling Claude Code to be docked in the Activity Bar (left/right), similar to other AI assistants.

Ideally:
• Provide Claude Code as a Side Bar view
• Optionally retain the existing editor-tab mode for users who prefer it
• Allow users to choose their preferred UI surface

Benefits
• Improves developer ergonomics and focus
• Aligns Claude Code with established VS Code AI UX patterns
• Enables persistent conversational context alongside code
• Reduces friction for users running multiple AI tools concurrently

Technical Notes (FYI)
This would require:
• Registering a viewsContainer
• Implementing a WebviewViewProvider
• Adapting the UI layout for Side Bar width constraints

Impact
This enhancement would materially improve usability for power users and teams using Claude Code as a daily development assistant.

Thank you for considering this request. Happy to provide feedback or help test if needed.
