[SUG] Better role management

[TudbuT]

(Example)

Is your feature request related to a problem? Please describe.
I can't edit roles.

Describe the solution you'd like
I want to be able to edit a role and also manage who belongs to the role. If possible, using buttons, so it's more visible.

Describe alternatives you've considered
I whould be okay with a text-based user and permission editor instead of a button-focused one.

Additional context
I don't have any.
