Problem

The "Get Next Editable" dialog is supposed to be a quick way to self-assign editables to edit. However it currently requires two steps - to first select the editable, and then to click "Assign to Self". Since the list also has a link to the editable, some people click on the link straight away and forget to self-assign. This means that, while they are reviewing, another editor might come in and assign the editable to themselves, wasting both of the editor's time.

Solution

Make it so a simple click on the editable self-assigns it to the editor. Secondary idea: show a warning when trying to download a zip from an editable that is not assigned to yourself.
