Hide directory structure for Project Tool Window?

Can I hide or shorten the display of the directory structure in the Project Tool Window? I usually have this window open on the left side fairly narrow and a long directory structure causes scrollbars. I don't need to see the location next to the folder. For example:

myproject.workalicious ~/Projects/workalicious.work/www/html/myproject.workalicious

Just seeing the myproject.workalicious in the Project Tool Window is enough for me.  The scrollbar at the bottom of the window isn't a big deal, just looking to make it go away...

Thanks,
Dave
