Navigation on internet web broswer provides usability that needs to be available on SAO
A "Ctrl + Click" or a "Wheel + Click" should open a new tab on the browser to be able to have "directly" 2 views available for different objets simultaneously.
A link should be available to directly jump to the selected view.
Example : demo.tryton.org/party/catergories/categories" or something similar
By clicking on the menu, you go to the menu, the url changes. If you "ctrl + Click" the browser like normal website, open a new tab and jump in the selected view.
Advantage : like this you can directly add bookmarks natively to the browser or shortcut to acces directly to the good view without navigating through the interface.
Advantage II : if you press "previous" you go back to the last view.
Finally : Opening "internal" tab should not be open unless a related objet view has been clicked by the user.
(SAO interface after 10 click, you get 10 tabs, and you get less space for the view)
Note : I dont know if I should post 2 discussions with the finally point. Let me know I can do this.
EDIT : Add advantage II
