I should be able to get a proper list of permissions, global and per board (and per album), for any given member, with a section in their profile area..
It gives you the general permissions and the 'all boards' permissions but lets you select different boards from a dropdown.
In the radio box list, I'd personally use dropdowns with an icon on each (green for enabled or enabled_own, red for disabled, another green or some blue for enabled_any). Sure, it's an extra click to change a permission, but then you can add deny permissions, right..? Unless you want to add deny for _own and _any separately, in which case, err...
If deny permissions weren't an option, I'd do what I did in SimpleDesk which was dropdowns with nice icons.
- I'd like to see the membergroups ajaxified... i.e. when clicking the link to modify their permissions, have it load under the permission name instead, so that you can even load multiple membergroups on one page, and then change them all in a row...
