About

A Chrome extension that merges multiple browser windows into a single window.

You can perform the following actions by clicking the extension icon or pressing `Alt + Shift + M`:
- Merge all normal windows within the same profile
- Merge all incognito windows within the same profile (requires incognito access)

After merging, tab groups and pinned tabs are preserved.

### Notes
- Normal windows and incognito windows are never merged together.
- If the shortcut does not work, you can reconfigure it at `chrome://extensions/shortcuts`.
- For enabling incognito access, see:
