I would like to suggest the possibility to give an access rule a functional name or show the documentation content on the access rule.
When you have a complex application that has many access rules it can be very tedious to see at a glance which access rule have what purpose, and which one you need to update.
For example, you might have multiple access rules for the same user role depending on a status/variable in the application.
There is the possibility to add documentation to the rule, but you have to click into the access rule to see it. You can also look at the xpath but it is not always easily understood or might have mistakes.
This costs a lot of time to analyse and it's difficult to manage these access rules. It seems like it would be a pretty small effort to fix!
