Redmine

Currently redmine allows to limit the amount of notification mails to be set in certain ways.

I suggest to add several other options (checkboxes) for the subcategory 'ticket'. Current there are three options to choose (status change, priority change, ..) plus the general update of a ticket.

I strongly suggest to extend those options to all default ticket options. This would include

- change of assignee
 - change of category
 - change of percentage done
 - change of closing date

Please consider this an option as there are many scenarios where too many mails are being sent.
