Member list & export & search

Hi all,

I'm working with CB 1.8 for some weeks and I'm quite happy with it. But there are some questions and I hope someone can answer them:

1. In the member list the items in the 3th column all have a fieldname. Where can I switch that off?
2. I would like to have an option at the FRONT END to export some fields of the user database to CSV or Excel. I'm working with Joomla 2.5. Does anyone know such an extension?
3. How can I switch off the title of the memberlist (class=contentheading, cbUserListTitle)?
4. How can I search in members using wildcards or parts of the name?

I hope you can help me!

Regards,

Joop
