From Johns Hopkins Uni:
I have a feature request. We have had several patrons who have complained about the Lean Library extension not working and/or asking if they can disable the popups. Can you add a setting or toggle so that users can quickly disable the extension? This might be an on/off switch or a list of options to disable for 1 hour, 4 hours, 1 day, 1 week, etc. I know several users have simply uninstalled the extension and that's not what we want to happen.
Ship notes: released with extension redesign
