Yes, please!  I can see the eventual addition of unread/marked article
totals (for subsumed groups) to the closed topic line in the group
buffer; implementing it this way allows for future functionality.

Another cool topics feature would be to allow interactive movement of
groups between topics.  I.e., we might overload Cut (C-k, C-w) and
Paste (C-y) so that the group gets inserted into the topic it was
yanked under.  This isn't very hard, we just have to add an entry to
the group parameter list at yank time.

The only issue is how to specify it doesn't belong to another topic.
For instance, you might have gnu.emacs.gnus under your `Emacs' topic
(having been put there via gnus-group-topics rather than a group
parameter), yanking this under your `Newsreaders' topics would leave a
copy under the old topic.  

Not a big thing, but it would complicate (and/or seriously slow down)
the update of read/ticked article counts (if they get added).  Hmm,
maybe add a parameter to indicate that the group should belong to just
the one topic?  Or just use the existence of a topic parameter to
determine this (i.e., ignore gnus-group-topics for such groups)?

Actually, the interaction between gnus-group-topics and group
parameter entries should probably be settled before doing the above.
