We are changing the usergroup permissions by editing the every usergroup now. But, that is very hardly if you have many different usergroup and if you change just for one option in permissions.
For example; if i want to change the "Delete post by self" option for all usergroups, i must edit every usergroup one by one and find "Delete post by self" option then select and save.
My request mean; it should be better if we select firstly "Delete post by self" feature in admin panel then set option of this feature to all usergroups at once.
Someone know that, this feature built in some other forum softwares And that feature is very very handy even if you have too many different usergroup...
