Find a simple list screen - Signature Keys or Task list being a good example.

Convert to use as much from ui framework as realistic,
test localization, test filtering, test sorting, test pagination, test multiselect... make sure we're not losing features and have a solid undestanding of how this works.

(Then create issues to convert all the other list screens.)
(May or may not want to use page/list-page as a midpoint, but convert too.)
