The new translation dashboard, developed as part of the mobile experience for Content Translation, is getting ready to become the unified dashboard to be used on both mobile and desktop. As a result, there will be just one dashboard and it will direct users to the desktop or mobile editors depending on the user platform (T328936).
This ticket proposes to enable the new unified dashboard on a test wiki to try this new approach before it goes to production wikis. The test wiki can be Test Wikipedia and/or other test instances where the tool can be tested on both mobile and desktop (i.e., Content and Section Translation must be available).
