Redmine has a nice batch edit feature, but nothing equivalent for "batch create" (please correct me if I m wrong!)
FogBugz lets you quickly create multiple tickets with the same properties (type, status, assignment, etc.) via a ajax-ified text box at the bottom of any filtered view of tickets. Tickets created this way match the values of the filter (and the filter grouping value - there s a text-box at the bottom of each group).
Toodledo has simpler option: it s "Add multiple tasks" feature is a textarea where each line is turned into an item.
Is there a redmine plugin out there that adds functionality like either of the above?
