Run tool window
The Run tool window displays output generated by your application. The appearance of each tab depends on the type of the application being run and can include additional toolboxes and panes.
If your application is running in the development mode on localhost, you can start debugging it right from the Run tool window. Just hold Ctrl+Shift and click the URL at which the application is running.

Pin tabs
If you are running multiple applications, each one is displayed in a tab named after the run/debug configuration applied. To preserve the output of an application, even if you re-run it, pin the output tab.
Right-click the tab and select Pin Tab.
To pin tabs by default, press Ctrl+Alt+S to open the IDE settings, select Advanced Settings and enable the Make configurations pinned by default option.
Split tabs
WebStorm enables you to split the active Run tool window vertically or horizontally.
Right-click the desired tab in the tool window and select one of the split options: Split and Move Right or Split and Move Down.
Another way to do this is by dragging and dropping the desired tab. WebStorm highlights the available areas in the tool window where you can place the tab.
To unsplit the tool window, right-click the top pane and select Unsplit from the context menu.
