[development] better autocompletion?

I'm not sure if this will be the right tool for the job in
comment_mover, but you should have a look at the activeselect module
(http://drupal.org/node/49976), which lets you link select boxes
hierarchically using AJAX. I don't really see how you can use a
hierarchy of select lists for comment moving, however, since nodes in
Drupal are not guaranteed to fall within any sort of classification -
by default they just exist in a 'big swimming pool'.

Perhaps you could use activeselect to browse hierarchically, first by
type, then by node, then by comment? (Assuming that you want users to
be able to move comments beneath specific other comments in a node,
rather than just 'moving them to a new node'). This would work, since
every node has one type (officially - excluding cases like event
module), and since every comment belongs in one node, and is
potentially the child of one other comment.

For the case of duplicate node titles, my advice is to not worry about
this, since it's too uncommon a use case to warrant making the
interface more complex.
