How can I duplicate (clone) a tab in IntelliJ Idea?
- Split Vertically
- Drag second tab to another Window/Monitor
You can't have multiple tabs for the same file without using split mode (vertical or horizontal). If you want a copy of the file, use Refactor | Copy.
To quickly split the view and make the same file visible in 2 splits hold Ctrl and drag the tab into the editor area.
UPDATE: feature request added, please vote.
