Sorting display of item

On large networks, a given biblio can have multiple items. For a given patron, it's sometimes hard to see at 1st glance if a book is available at his own branch. This RFP want to improve the display of items.

• highlighting : if a patron is logged in, or if the branchip of the computer the patron queries is at a known branch, we can highlight all items owned by the branch.
• hiding : some libraries may also want to hide completly items that are not in the branch of the patron (or branchip). A syspref could be added to activate this feature. If activated : in the result list, only the patron branch (or branchip) would be displayed. In the biblio detail same thing, but a click let the user see other items.

In 3.0, when a user query a given branch, the result list display only biblios with an item at the selected branch, but it also display other items. It is considered as unclear by most libraries. The list should show items at the selected branch, and the detail should do the same (with a click to let the user see other items)
