Use this page to configure the appearance of the editor tabs and tab headers, specify their positioning on the screen, and define the opening and closing policy.
|Tab placement||Use the list to set the location of editor tabs. If you select None, no tabs will be displayed, and any new file will open in the current editor.|
|Show tabs in one row||Select this option to see the tab headers in a single row.|
|Hide tabs if there is no space||If this checkbox is selected, IntelliJ IDEA shows as many tabs as the editor width allows; the rest are hidden and available under the Show Hidden Tabs selector. Clear the checkbox if you don't want to hide any tabs. Alternatively, you can choose from the main menu to see hidden tabs.|
|Show pinned tabs in a separate row||Select this option to automatically arrange pinned tabs in one row and unpinned tabs in other rows.|

If this checkbox is selected, the font size on the editor tabs is set to the smaller value.
If this checkbox is not selected, the font size on the editor tabs is set to the default value, as in the project tree view.

|Sort tabs alphabetically||Select this checkbox if you want the names of editor tabs to appear in the alphabetical order.|
|Open new tabs at the end||Select this checkbox to open a new tab at the end of the already opened one.|
|Enable preview tab||The preview tab allows you to view files in a single tab one by one without opening each file in a new tab. Any other file that you select will replace the previous one in this tab.|
|Open declaration source in the same tab||When you navigate to a method, class or a variable, the source file that contains their declaration will replace the current tab if there are no changes.|
