Drupal 6.x has autocomplete form functionality built-in (I think using jquery). It would increase usability to automatically complete searches for plugins using drupal's javascript framework.
I tried researching it, but couldn't find any documentation on it. It's probably hidden some obscure place. Perhaps someone who is familiar with it can help implement this functionality.

philbar commentedThis functionality will be like the Project field on the Issue reply form on this page.
See: #106950: Use autocomplete field for project selection on issue tracking pages
And the patch they applied for the functionality:
#201435-27: Huge list of projects hard to use, consumes excessive d.o. bandwidth, can hang browser
Hope this helps!
