It should be possible to change who a bug is assigned to, as well as marking it as other states in a single transaction, not the current two changes it takes right now. For instance, changing a bug from 'Assigned' to 'cturner' to 'Needinfo' to 'foobar' should be doable in the same step
I am closing this bug report as there has not been any activity on this for a while and there has been various changes made to bugzilla in the meantime. If the issue still exists, kindly reopen it. Thank you.
