Everything that is explained in the mockups, plus:

• 'Account' select details:
  • typeahead
  • 20 most recently created {items} displayed in the dropdown menu (sorted by most recent)

  • When "View all {items}" is clicked, open a modal dialog that includes a paginated table listing all {items}
    • display 5 {items} per page
    • sort table by last updated by default
    • make table filterable by {item} name

• When 'Application plan' select is clicked, display all Application plans for the selected Product in the dropdown menu (sort them alphabetically)
• If no Application plan exists for the selected product:
  • disable the select
  • and display an inline warning text with following copy: "An Application needs to subscribe to a Product's Application plan, and no Application plans exist for the selected Product. Create a new Application plan", where the "Create a new Application plan" portion of the text is a link to the {Product} > Applications > Application plans > Create Application plan page
