There is some information on Blogs and SDL LiveContent about creating GUI Extensions.
What I am looking for is an example of an extension which uses the SearchView results screen.
I want to create a button which calls the Tridion search (perhaps twice) with a custom search pattern, aggregate the results and display it in the SearchView results screen. Inspecting this SearchView in Chrome shows that it is a div with id FilteredItemsList.
Any thoughts or suggestions are welcome...
