A user can see his GitLab group permissions (if he is a direct group member) on the group overview page - but for the projects overview page the own role / permission level is not listed.
If a user is a member of a GitLab project but not of the corresponding group of the project - how can this user see his project permissions? Is there any way for a user to see his own permissions in a GitLab project? Can such a user see the other participating project members?
GitLab version is 8.5.7 CE.
This feature was added in the meantime (having GitLab version 10.x while writing this answer). The members page of a project now lists the permissions for all members (direct project members and inherited group members).
