If in integrations i klick on [ + add integration ] the integration list opens and the cursor is in the search field, so i can start searching - very nice 
If in addons i click on [ + add addon store ] the addon store opens, but the cursor is NOT in the search field. And the blue addon store button looks like adding an addon store with the plus in the icon.
What about the search field beeing activated on loading pages like automations, developer tools/states and so on?
