When IndependentBranches is ON, the staff can search for result all libraries. (We have a Limit OPAC search in their own branch only, but don't have Limit STAFF search). And when staff open a item belongs to another branch, they still can change it, change record, item and status... Far more than this, they can see patrons, who place hold or borrowed this item, and by this way, they can access to these patrons, and still can change their password, upload another picture... Please remember that, staff can't search patrons, check in-out for patrons belong to another libraries, when IndependentBranches is ON, but by above way, they can find some patrons and can access their profile.This is not Independedent at all. We can solve this problem, make totally Independent Branches, if we can add a preference like "Limit Staff search on their own library, where they are registed."  In relations, i want to talk about "Refine your search", where we can choose branch library, where results belong to. So maybe it's not hard to make a preference like that. More than this, i checked out, in Koha 4.12 (Koha.org), they added this feature. So i hope someone can do it. I specially thank Waylon Robertson <wrobertson1981@yahoo.co.nz> for paying attention and help.
