"Back" button for using linked elements

Hi,

If you are looking at the detail of object A, then click on a "linked element" B, object B is opened.
It would be nice if there was an easy way to go back to object A, such as a "back" button.

Since we now have a unique ID to access every object, maybe this is possible without too much difficulty ??

Another option could be to open object B in a separate tab, for example. Or opening object B in a pop-up window (?).

What do you think ?
