Changing the tabs per row
Open the settings for the notebook. Notice that, unlike the PM Notebook and OS/2 - Windows Notebook, the Windows Notebook does not support:
Binding styles
Changing orientation
However, you can modify the number of tabs per row and the tab height. Type 5 as the value for tabsPerRow and select OK to save the changes. Your tabs now appear as a single row of tabs in the notebook.
