Nested menus and tabs confusion
The combined top nav menu, 'Kea Apps' tabs, and then the list of daemons below that, was confusing. Cathy commented that while she liked the fact that she could open tabs here and leave them open, there were so many layers of tabs she wasn't sure what related to what.
This could be somewhat ameliorated by using the same names for the app in the upper set of tabs and the title of the lower panel. Here the upper tabs are labelled 'Kea@hostname' but the title of the panel below is 'Kea App'. It would help to allay confusion if we used the same identifier in both places.
