 // tab should have its own copy of the toolbar. Right now, we decided to leave
 // it like this as he expects it will make it easier for him to implement
 // tab dragging and tear-off into new windows. It's also not very expensive.
 // As we hook things up, we'll see if this imposes other restrictions (such
 // as command-handling or dispatch) that will require us to change the view
 // layout.
+// TODO(jrg): Following on to pink's comments... each tab does in fact
+// have its own ToolbarView.  Similarly, each also has its own
+// BookmarkView.  That makes things marginally more expensive.
