It'd be helpfull to add a link to go backward to the last visited page.
Now, we have an history bar to see the last visited objects.
With history bar we can go the last visited object's default page.
Here I'm suggesting the last page (equivalent to the Browser backward button).
People are used to the browser backward button. Adding another button to do exactly the same think will juste get them confused, not to mention that it will burden OpenPLM interface.
The backward button works perfectly with every page in OpenPLM. And for those who want more, there is the history bar.
