-            Semantically, the [=file handler/icons=] are used to convey the

-            this is typically only displayed when the app has become the

+            collection of images at different sizes) that represents all files
+            that are associated with the handler. This will typically appear
+            like a document (e.g. a piece of paper) as opposed to an
+            application logo, but might include elements (such as logos) that
+            suggest which application the file is associated with. As with
