Cinema 4D offers 2 ways of doing this: - You can assign a **To Do** tag to specific objects - Timeline markers offer a **Task** option\ Comments can be added at both locations. The **Project Settings** menu offers a **To Do** tab in which all of a Projects comments added to the above mentioned locations can be collected and viewed: ![Image: 035550.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/035550.jpg)\ Comments collected from tags and Markers are displayed in the **Task** tab and can be set to **Done** in the corresponding tab. The **Task** and **Done** tabs are shown in the image above. The **Task** tab contains all tasks that have not been completed, which can be moved to the **Done** tab (and back to the **Task** tab, if necessary) when completed. > **Tip:** Tip:Note that elements added via XRefs cannot be marked as **Done** in the master file.
