I like to use multiple tabs so I can switch quickly between different parts of my application. To do so It’s important to identify behind which tab I can find something. At this moment there is noting what separates one tab to another when I have three tabs open of one application.
I suggest using a more descriptive page title name. In the page editor, I like to see the name of the page. In the settings, I like to see the name of the selected tab. Etc Etc
