Within Teamwork, you can choose which features you want to enable on each of your projects.
To manage project features, go to the Settings tab of the project and select the General subsection.
In the General tab, you will see a section for Project Features. Using the toggles to the right of each feature, you can customize which sections should be enabled or disabled for the project.
Note: Once a feature is disabled in the project settings, it is removed for all users on the project. The tab for that feature will no longer be visible in the project's navigation menu.
