[Feature] Global search

[micdah]

Another great feature in the Kubernetes Dashboard, is it's global search feature, whereby you can search for any resource type by name across the selected namespace(s).

The current filter only filters the selected view (and is sticky, which is not what I had expected, meaning when I choose pods from the navigation menu it keeps the search term and filters the view by it, I would have expected the search to reset when using the menu navigations).
