🗂️ Tab Shortcuts Extension

A Chrome extension that enhances browser productivity with keyboard shortcuts and UI controls for tab management and GitHub workflow optimization.

🛠️ Features

This extension provides the following functionalities:

• Duplicate Tab: Creates a duplicate of the current active tab (shortcut: Ctrl+Shift+D)
• Pin Tab: Toggles the pinned state of the current active tab (shortcut: Ctrl+Shift+P)
• New Tab Here: Opens a new tab immediately after the current one, linked to it as the opener so closing it returns focus to the original tab (shortcut: must be configured)
• New Tab Here (Background): Same as above, but the new tab opens in the background (shortcut: must be configured)
• Prevent Tab Close: Prevents the current tab from being accidentally closed (shortcut: must be configured)
• Collapse Translation Files: On GitHub PR pages, collapses all translation files (*.json with 2-letter language codes) to reduce visual clutter (shortcut: must be configured)
• Convert Relative Time: On GitHub pages, converts relative time stamps (like "2 hours ago") to absolute time format (like "10 September 2025, 10:15") (shortcut: must be configured)

All features can be accessed via:

• Keyboard shortcuts
• Extension popup menu (click the extension icon)
