It will be better if you can add this feature to segment autotags like (category 1, category 2) and under each category there will be several independent autotags. Currently i have 20 autotags and want to group them into 3 category but that is not possible. These are some suggestion how to implement this.

1) In Timesheet: It can be added in timesheet generation and giving an option to group autoatags and it will show total time spent under each category.

2) In Timeline: It can also be displayed in autotag timeline and user will have option whether to show all autotags or category of autotags.

3) In autotag editor: The user can be given an option to categorize their autotags and based on these category data will be displayed in timeline and timesheet.

Thank you.
