Feature Request: Interactive Status Bar for Dynamic Model Switching

Problem

Currently, users can monitor their model and context usage via the status bar (e.g., Claude 3.5 Sonnet [======] 30%), but there's no quick way to switch between models (Haiku/Sonnet/Opus) during a session.

Current model switching options:

• Edit ~/.claude/settings.json to set a default (set-and-forget approach)
• Use model="haiku" parameter when spawning background agents
• No way to dynamically switch models for the active session

Business Value

Model selection directly impacts:

• Cost savings: Haiku is ~10-20x cheaper than Sonnet for simple tasks (file searches, running tests, straightforward fixes)
• Speed: Haiku is significantly faster for quick operations
• Quality: Opus provides superior reasoning for complex architecture/debugging (pay more, get better results)

Business owners need this control. The three models exist for strategic use - let users leverage them dynamically, not just set-and-forget.

UX Inconsistency

• ✅ Workflow modes (Plan/Ask/Auto) are easily accessible in the UI
• ✅ Status bar shows model info and context usage
• ❌ No UI control for switching models

The status bar displays model information but isn't interactive - this is a natural place for a model switcher.

Proposed Solution

Make the status bar interactive:

1. Click status bar → dropdown/menu appears
2. Color-coded models for instant visual identification:

• 🟢 Haiku (green) - fast/cheap
• 🔵 Sonnet (blue) - balanced
• 🟣 Opus (purple) - powerful

1. Visual confirmation: Claude announces the model change before proceeding

• Example: "Switched to Haiku - optimizing for speed and cost"

1. Mid-processing handling:

• If processing, either queue the change for next request OR
• Prompt user: "Currently processing - switch model after completion?"

Expected Impact

VS Code users will appreciate dynamic cost/performance control that matches their workflow needs in real-time.
