For older kids.

There is not a different look for the teens option.
I want to supervise my 13 years old but as she is used to Outlook, she finds KMail very limited. She would like to be able to separate her contacts into different lists, be able to add notes to a contact in her list (Like their date of birth, their address, etc.), create Groups (Mailing List), flag an e-mail as important so she get back to it easily later, flag an outgoing e-mail as priority so the recipients sees that it is very important, etc.
Love it and support you greatly!
