Newsgroups displayed as tree?

[Iain Hallam]

I'm on Win32 with 0.9.5, and I have subscribed to some 50-60 newsgroups 
on my ISP's server. It's getting a mite difficult to locate which a.b.c 
means what. Would it be possible to display the newsgroups as a tree 
(something like the IMAP or POP accounts that I also have)? I'd imagine 
something like the following:

v-[ ] news.f9.net.uk
    v-[ ] netscape
    |  v-[ ] public
    |     >-[ ] mozilla
    v-[ ] uk
       v-[ ] comp
       |  |-[ ] homebuilt
       |  '-[ ] misc
       v-[ ] local
          |-[ ] bristol
          >-[ ] london
