The default behavior for the Navigation block in d6 was to replace the word Navigation with the user name. It appears that this logic was removed from the core user module in d7. My client stills wants the user name to display. Is there a way to duplicate this same behavior in d7 ??
What complicates things a bit is that we are using a mini panel that includes that block but I haven't figured out a way to override the title with the user name. I've tried using the user:name token as the Navigation block title and then overriding the title with %title but it displays the literal value 'user:name' instead of the actual user name.
