Ability to order activity types in the emails & activities widget.

Each user on our CRM shares some basic activities, however there are some users who have an activity they want to track but does not apply to anyone else. In this case the ability to reorder the activities and edit them after being added similarly to the customization that is available on a status column or dropdown column would be very useful. This would allow you to place activities that do not apply to you at the bottom or even just group activities by user. Thanks!
