Upgrade: How to get "all unassigned tickets" to show up in At a Glance?

I upgraded from 3.4.2 to 3.6.5 and everything seems to work fine. (on Linux

In the At A Glace preferences I do not see a listing for un-assigned

Is there a way to see this? I mean I would like to set that up so that the
At a Glance page is similar to the default page in 3.4.2… I made a search
for ‘new’ tickets but that is not exactly what I need…

Any help is appreciated.
