filing messages

Hello,

I am migrating from Netscape 4.7 to Netscape 7 and I found that now with 
the new version if you want to file a message when you click on the FILE 
  icon you get the first window with a list of your mail accounts and 
then when you choose the account you get the list of all your folders in 
one             column. The problems comes when, like some of the heavy 
users, have hundreds of folders and in order to find the right one they 
have to scroll up and down for ages.
With older versions of Netscape you had all your folders in one window 
positioned in multiple columns.

Is there a way to get the same with Netscape 7?

Thanks a lot.
