Comment 1 for bug 1981739

Here's a patch:

https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/berick/lp1981739-patron-neg-balance-ang

1. Displays patrons whose home lib is a descendant of the selected lib, so selecting the root shows all patrons.

2. Org select is sticky / grid prefs settings.

3. Adds paging support to the API so it will play nicely with grid paging.
