notebook tabs

[stan <s4chang student math uwaterloo ca>]

greetings -

is there any way to have multiple rows of tabs for a notebook instead of
just one row of tabs?  i have a notebook container set up, but the tab
label names are a little long which causes the notebook to extend past the
maximum width I have set for the window.

is there a work around?  can any one suggest a method i rearrange it so
that i can display all the tabs without having to resize the tab labels?

thanks in advance
