Many users produce content in one language and need to maintain an up-to-date mirror of that content in another language. It would be useful to have a plugin that performs the following tasks

• automatically adds the label 'for-translation' when a page is edited
• add a new tab in Browse Space called 'Needs Translating' which lists all pages with the label 'needs-translating' and the last update date. Include a checkbox for each page plus 'Check All' to allows bulk marking as updated.

Users will be able to mark a page as updated by deleting the for-translation label when viewing the page content. For themes that display a list of the page labels on the view tab, this only requires a doubleclick on the label delete. Users can use existing notification scheme to receive notifications when a page is labelled with 'needs-translating'.

Use Case
1) User A updates a Page A in the English space as normal
2) User B is emailed is with page update notification, triggered by the label 'needs-translating' being added Page A
3) User B views Page A in one window while they edit Page B, which is the translation of Page A, in another window. When Page B has been updated, they click the delete button for the 'needs-translating' label on Page A

This is only one approach and attempts to use existing functionality as much as possible.
