Add a Right Click option called "Duplicate" on Tabs , and on Selected Text, in the editor. "Duplicate" on a Tab will copy the full contents of the tab into a new tab directly to the right of the current tab -- inserting between the right-clicked tab and the tab that is to the right, if there is one. "Duplicate" on Selected Text in an editor will copy just the selected text into a new tab directly to the right of the current tab -- inserting between the right-clicked tab and the tab that is to the right, if there is one.
