[FEATURE] detailed description pane

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Description

Currently, viewing the "thinking" mode and detailed transcript requires pressing Ctrl+O to toggle the view. This interrupts workflow and makes it difficult to monitor Claude's reasoning process in real-time.

Proposed Solution

Proposed Feature

Add an optional persistent pane on the right side of the terminal window that always displays:

• Thinking tokens (extended thinking/reasoning)
• Detailed transcript of the conversation

Alternative Solutions

Ctrl + O but it would be great to not have to interrupt workflow with this mode

Priority

Medium - Would be very helpful

Feature Category

Interactive mode (TUI)

Use Case Example

Proposed Feature

Add an optional persistent pane on the right side of the terminal window that always displays:

UI Concept

┌──────────────────────────────────┐

│ Main conversation area │──────────────│
│ │ <thinking> │
│ │ Let me analyze... │
│ │ </thinking> │

Benefits

• Monitor Claude's reasoning without interrupting the main view
• Better visibility into tool calls and decision-making process
• Useful for debugging, learning, and understanding Claude's behavior
• Optional - users who prefer the current behavior can keep it

Suggested Implementation

• New setting to enable/disable the side pane (e.g., showThinkingPane: true)
• Keyboard shortcut to toggle pane visibility
• Configurable pane width
• Thin border separating panes for minimal visual noise
