Adding and Removing group members can be challenging and error-prone via Set-OpenADObject, especially when the existing membership list is over 1400 members. The Microsoft ActiveDirectory module simplifies these actions with the Add-ADGroupMember and Remove-ADGroupMember commands.
Adding similar capability to this module would be a fantastic usability gain. Following current naming patterns (which mirror the ActiveDirecotory module's commands) the matching commands would potentially be Add-OpenADGroupMember and Remove-OpenADGroupMember.
