As I said in another post, the option was removed, sadly, as I 'd use it several times a day.

It'd just adds flexibility and ease :

- you want to see that parent separately ? 

- those siblings ?

- that specific tagged item ?

- that children ?

 

.... you can of course click on it/them to show it/them in its/their home grid(s) or in the/their current grid 
But it would be great to also be able to right click and select "Show item in a new scratch grid"

 

A lot of bang for the buck.
