Redmine

Currently Redmine is missing hook which would allow adding custom tabs to project settings menu. Attached file is a patch adding such hook named helper_projects_settings_tabs.

I know that there are ways to do this... But in this case you cannot install many plugins using such technique. Read also: http://www.redmine.org/boards/3/topics/20208

It's really important to me and I plan to use this hook or similar solutions in my plugins. I even have written a plugin providing this hook. :)

Of course, a better solution could be using MenuManager for project settings tabs...
