// You'll notice there is no explcit api for making a tab a mini-tab, rather
// there are two tab types that are implicitly mini-tabs:
// . App. Corresponds to an extension that wants an app tab. App tabs are
-// identified by TabContents::is_app().
+// identified by TabContents::is_app(). App tabs are always pinneded (you
+// can't unpin them).
// . Pinned. Any tab can be pinned. A pinned tab is made phantom when closed.
// Non-app tabs whose pinned state is changed are moved to be with other
// mini-tabs or non-mini tabs.
