How do I remove/relocate/customize buttons in the title bar?

Solution 1:

Most of the Title Bar is not subject to easy customization an Microsoft does change what is displayed, where, from time to time, without notice.

However, in Windows systems, you can change or move the Quick Action Toolbar (QAT) portion to below the Ribbon.

Click on the Dropdown menu for the QAT. At the bottom you will find the command to reposition the QAT to under the Ribbon. It will then appear between the Ribbon and the Ruler.

You can also, under that drop-down add or subtract items from the Quick Action Toolbar.

Here is my webpage on Modifying the QAT if you need more.

You can also click on the document's name to drag the window.

Here is the titlebar, ribbon, and QAT displayed with the QAT below the Ribbon. As you can see, moving the QAT provides a lot of room (and also allows for much more room on the QAT).
