Assegnate 4 su 5 stelle

Just by installing this theme, I can get TB11 menu bar back to the top maintaining the mail bar inside the tabs.

Still, I would prefer to keep the Aero style buttons instead of going back to TB3 style buttons.

Questa recensione riguarda una versione precedente (1.0.1.0) del componente aggiuntivo. 

Feel free to install another theme then, that's what the whole theme-thing was made for - every user selects the theme he likes the most ;)
Note that as you already pointed out in another rating there are userchrome hacks to archive what you want - without a theme change.
