Autocomplete ticket fields


This plugin auto completes user info when input report, owner, cc in ticket, and provides a popup dialog to edit cc to help input multiple recipients. The user information are maintained in Trac instance's ../conf/username_list.txt file.

This plugin is designed to be used in enterprise environments, where there may be hundreds or thousands of users who are potential notification recipients. Trac administrator should maintain a full list of users and their full name, instead of using Trac's built-in user list.

Alternative plugin: AutocompleteUsersPlugin, that uses Trac's built-in user list to accomplish this purpose.
