If there is insufficient space to display all the sheet tabs, you can increase it by pointing to the separator between the scrollbar and the sheet tabs, pressing the mouse button and, keeping the mouse button pressed, dragging to the right. In doing so you will be sharing the available space between the sheet tabs and horizontal scrollbar.
