For WP menus-
1- allow adding mulitple menus to template- example- above header, below header, in footer, etc.
2- styling the menus individually
3- styling menus in page templates
Now there is a custom menu widget that you can place anywhere and can create desired number of custom menus.
I totally agree. Menus serve to separate and organize a pathway for the end-user.
For instance in the site I created http://www.dmnphoto.com , you will notice that I have a menu: at the top, under the header, one in the footer. 3 menus styled differently (It was a pain for me to to this in the program I used). Would be a fantastic edition to TT and would go a long way to separate TT from the "other" guy (I used 2 votes for this one).
