Yesterday, i've been searching the reset role button (i knew the feature exists, but didn't find where) for 30 minutes...
As said in this discussion, if you want to reset a role, you can go to Site Administration -> Users -> Permissions -> Define Roles. Select a role name and then press the Reset to defaults button.
I think it's not very logical to not find this button on the editing role page, that would be more suited!
The reseting role button should be added (or moved) to the editing role page.
Am i the only one to think this ?
