Claude Chat Width Customizer de DoubleGate

More screen. More Claude. Give your conversations room to breathe—expand the chat area from 40% to full-screen width with an intuitive slider or one-click presets. Perfect for ultra-wide monitors and power users who want more from every session.

Key Features:
- Adjustable slider for precise width control (40-100%)
- Quick presets: Narrow (50%), Medium (70%), Wide (85%), Full (100%)
- Real-time preview as you adjust
- Theme support: Light, Dark, or System (follows your OS preference)
- Instant sync across all open Claude tabs
- Sidebar-safe: Only the main chat area changes—navigation stays untouched
- Privacy-first: All settings stored locally, zero data collection

How It Works:
Click the extension icon while on claude.ai, drag the slider or tap a preset, and watch your chat expand instantly. Your preference saves automatically and persists across browser sessions.
