Hi - For our multi-site implementation we have roles for each site, and as we have a large number of sites, we have a large number of roles.
We wanted to implement a new naming standard for roles, which would correspond with a similar naming standard for site names. Where modifying site names is existing admin functionality, you cannot modify the name of a role. The only option is to create a new one, and delete the old.
The UX for roles differs from many other admin functions. Even though there is only one field, having the form field appearing in the bar at the top of the page is inconsistent and resembles a search field, which is what I thought it was the first time I saw it. Modifying a role name is something that should exist - any label should be able to be modified for this reason.
As a result, we are going to have mixed naming standard and non-standard role names. I'd welcome some insight into why this is.
