I like to have my contacts sorted by First Name, then Last Name. This can be done by dragging the First Name field around and sorting the list. However this always goes back to the default Last Name, First Name.

Also, when I am composing a message and want to select the recipient, the contacts are sorted by Last Name, First Name. I want to see First Name, Last Name.

Can there be a user setting option that can override these? [....]

Along with Organizer, File Storage, Forum, and Brainstorm buttons - please add a Notepad-like feature. It should be similar to Windows Notepad or Windows Outlook Notes with limited features. A basic feature to save simple text messages. Thanks for a great product! [....]

It would be a nice feature to be able to change the way the date is displayed in the mail interface. At present it is U.S. style (mm/dd/yy), us europeans would prefer (dd/mm/yy). Many thanks. [....]

The other day I attached files and after realizing I attached one extra file I didn't need I found out that GMX had no option for me to remove the attachment, this is my only complaint about the interface, unless for some reason I did not see the option to click remove attachment... [....]
