There is the following screen:
Site administration -> Users -> Permissions -> Define roles
In that screen, the administrator can control the precedence of the roles by clicking the "Move down" and "Move up" arrows buttons. It seems that such changes affect the display order of the roles in the following screen:
Site administration -> Users -> Permissions -> Capability overview
And the display order effect is exactly what I'm looking for.
The thing is, I wonder if there are other effects beside this one, in the context of capabilities and permissions, that make some roles "stronger" than others because of the difference in their positions in the "Define roles" screen.
According to these help topic:
https://docs.moodle.org/38/en/Managing_roles#Manage_roles
which include the following text:
"The 'Manage roles' tab contains a list of roles on your site. The edit column contains icons for editing, deleting roles and copying roles, and for moving them up or down in the list (affecting the way that roles are listed around Moodle)."
The only effect is in a display one.
However, because this is a change in something so profound in a Moodle system, I want to be sure before doing that.
Could you please share your knowledge and experience?
Thanks
