ClickTabMove by PKxk8J

You can move tabs to another window or a new window from the right click menu on tabs.

Not only moving the clicked tab, you can move

• Tabs on the right side of the clicked tab
• Clicked tab and the right side tabs
• Tabs on the left side of the clicked tab
• Clicked tab and the left side tabs
• All tabs
• Tabs selected in a popup window

By moving all tabs in one window to another window, you can merge two windows.
Pinned tabs remain pinned after moving.
Optional notifications show progress.
