Since the locators for the other tabs are already defined, it makes sense to go ahead and add them to navigation tree here:
```clojure
(nav/defpages (common/pages)
  [::page
   [::new-page [] (browser click ::new)]
   [::named-page [content-view] (nav/choose-left-pane content-view)
    [::details-page [] (browser click ::details-tab)]
    [::content-page [] (browser click ::content-tab)]
    [::filter-page [] (browser click ::filter-tab)]
    [::views-page [] (browser click ::views-tab)]]
```
