Sometimes you wish to remove a widget altogether from your system, so that users do not use it, or to free up the template.
To do that ...
i) Navigate to the template's settings page at:
Site administration -> plugins -> filters -> Poodll -> templates -> [The template you want to clear]
ii) Choose "(A) Clear Template" from the "Autofill template with a Preset" dropdown.
(hint: it's the first item in the dropdown)
III) Scroll to the bottom of the page and press "Save changes"
