Redmine

At current version Redmine we have standart sorting issues in Gantt chart by Issue ID.

Also we have a plugin provides order tasks by time: http://www.redmine.org/plugins/redmine_smart_issues_sort

But i think sorting/grouping must be optional. I need to group/sort tasks in Gantt chart by users (and second sorting by time, as in plugin).

Yes i know, i can set a filter and see all tasks by concret user, but it is not usefull, i need to see all map.
