Almost all activity in ftrack is logged, whether it’s creating of tasks or note categories, assigning of resources to tasks, updating statuses etc.
The activity feed can be found:
as a tab in the sidebar.
as a widget on the My Tasks dashboard.
as a widget on a custom dashboard.
What’s included in the feed depends on the context. If you’re in the sidebar of an object, all activity on that particular object is included. If you’re on your My Tasks dashboard, all activity on tasks related to you is included.
