In 24.05, libraries can no longer filter the holdings table in the staff interface by shelving location since the Home library column is now a drop-down instead of allowing free text entry. As of 23.11, the filtering was free text instead of a drop-down, which meant that libraries could type a library name *or* a shelving location to filter. Additionally, the holdings table search bar doesn't appear to 'read' shelving locations, so libraries can't use that to pinpoint items with a specific shelving location either. This will likely be moot with Bug 15461 - Add staff equivalent for OpacLocationOnDetail, but in the meantime, it isn't user-friendly for libraries who need that column to filter bibs with many holdings.
I agree that this is very inconvenient problem. I hear from staff members regularly about how this is something they feel they should be able to do (and were able to do before the last upgrade). Bug 15461 does appear to solve this and is a great solution. I'm advocating for the bug to be QA'd soon.
