Manage project managers and members
You can always change the permission or revoke access of someone to the entire project.
Go to start screen of the yoheim app, or create a new tab where you would be able to see the list of your projects.
Open the context menu of your project and click on members.
You would see the following dialog. Here would be seeing the list of people who has access to your project.
You can click on edit and see the following dialog
Here you can change access type of a member to Manager or Member.
The reason we have manager role in project level is because, only managers and owners can create, modify or remove any resource. So if you are a team owner it would be really difficult for to keep managing all the resources in all of your project, with this you can have managers who can create delete or modify resource in the respective project.
