Before upgrade to version 10 (v10.1.7), I can type "project apple" in the search box and then select the "Notebook:project apple" suggestion from the dropdown.
Now after upgrade, it seems to require quite a few more steps to do the same thing:
In search box, input "project"
In the dropdown, the "project" entry only appear under the "Goto..." section, but not the "Filter" section. So I select "Goto... project"
Select the search box again
Now the suggestion "project ... add filter" appear. Select this to add the notebook filter.
Select the search box again and input "apple"
Is there faster way to do this? It helps to at least show "project" under the "Filter" section in steps (2).
