I'd like to give some different permissions to special groups I have created for viewing the terminate work flow buttons in admin mode. How can I change who can see the terminate and terminate all buttons? One group should not be able to terminate workflows. I realize I can catch the terminate event and process that way and output a message if they don't have terminate permissions but I would prefer to not even show those users the terminate buttons. I already have methods to get group membership and permissions of users for my custom membership provider.
