make about:tor more userful
If you have any probema with the configurations of proxy or something, the page about:tor could tell it instead to give a friendly message, which could confuse or mislead a layman or distracted User, I think just the Torbutton logo not enough.
It's like a joke that "You are now free to browse the Internet anonymously.".
In the logo should be changed.
Of course sometimes it if possible, and only a suggestion, perhaps an alert can serve what can not and be as "friendly" as well.
