You must be kidding... WTF???
Couldn't you include it into the 1.4.6? Do I need to look for it manually?

Guys... I'm begging you...

You need to change the favorites link on the theme you are using (which you didn't tell). That link is generally in the footer.

It's the default theme, just with color changes...

OK, thanks.
