<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>In multilanguage sites, Seven and Claro display the node translation language in the title of the edit page. However, Gin does not show the language anywhere in the UI. The only way to tell which language you are editing is by looking at the window/tab title or the langcode in the browser address bar.</p>
<p>This makes it more confusing and error-prone for content managers to input translations, since it is not easy to tell what language is being edited. This is especially true if the site has 2 or more alternate languages besides the primary language.</p>

<h4 id="summary-steps-reproduce">Steps to reproduce</h4>
<p>1. Start with a Standard profile Drupal installation.<br>
2. Enable Language and Content Translation modules at /admin/modules<br>
3. Add one or more additional languages at /admin/config/regional/language<br>
4. Enable translation for Basic Page at /admin/structure/types/manage/page<br>
5. Create a Basic Page at /node/add/page<br>
6. Create a translation for the page. Note that the language of the translation is not displayed while creating the translation.<br>
7. Edit a translation for the node. Note that the language of the translation is not displayed while editing the translation.</p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Add the language of the translation back to the page title as in Seven/Claro, or come up with another way to clearly display the language of the translation in the UI of the edit page.</p>
<p>Also consider the issue for all translatable entities, not only content nodes.</p>
