Comment(by garycmartin):

 Home View, ListView currently shows a blank white canvas when a query has
 no matches, it should really behave like the Journal with the 'No matching
 ....' UI or users who randomly/accidentally press keys and generate a shel
 query without realising it will not understand the blank UI state. See
 attached mock up image showing the list view with 'No matching activities'
 feedback UI.
