Customizing format bar?

Hi there,
[Apologies in advance if this has been asked and answered! I could find an answer in a search of the forums…] I would like to customize the format bar, but the only customization option I can find is for the toolbar. Is it possible to customize the format bar as well, or just the toolbar?
Thanks a bunch!

It is not possible to customise the format bar, and there are no plans to add that capability. The limitation is largely technical.
