You're right, the size of the tabs increases a lot if the folio title is very long.
I don't know if it will be possible or easy to truncate the folio name in the wiget header if name was so long.
But if you place the mouse cursor on the header tab with the scroll mouse you can navigate quickly even if the header tabs are larger, or use page down/up keyboard touch keys for quicly navigating (the keys depend on your operating system).
