Support Ctrl+Tab for thread history navigation

What feature would you like to see?

Summary

I would like a keyboard shortcut to navigate thread viewing history using Ctrl+Tab (and Ctrl+Shift+Tab).

Similar to the behavior in Atlas browser, this would allow users to quickly switch between several recently viewed threads.

Motivation

• I frequently move back and forth between multiple threads
• Being able to quickly return to recently viewed threads would significantly improve workflow efficiency
• Keyboard shortcuts are faster and more efficient than mouse-based navigation

Desired behavior

• Ctrl+Tab: Move to the previously viewed thread in history
• Ctrl+Shift+Tab: Move forward in thread history
• A history of several recently viewed threads should be maintained
• Threads should be navigable entirely via keyboard

Use cases

1. Run a prompt in thread A → work in thread B while thread A is processing → press Ctrl+Tab to immediately return to thread A
2. Move back and forth between multiple threads for comparison using only the keyboard

Expected impact

• Faster navigation between threads
• Improved keyboard-driven workflow
