toggle visible groups under a topic?

[leon]

Hi all,

Here is a thought:

Gnus hide the groups with no tick, dormant, new articles. When I want to
post to a hidden group. I usually hit 'L' and look for the group and
post to it. Is there a better way?

Can anyone cook a elisp function to toggle visible groups under current
topic in group buffer.

Thank you.
