Comment 4 for bug 1766262

Here is a list of settings that don't appear in any non-XUL code in master (to the best of my understanding). This includes those mentioned in the original bug report. Are any of these being used in a secret location, or possibly will be supported in the web client soon?

acq.fund.balance_limit.block
acq.fund.balance_limit.warn
acq.holds.allow_holds_from_purchase_request
circ.auto_hide_patron_summary
circ.hold_expire_alert_interval (see bug 1688356)
circ.hold_stalling_hard
circ.holds.target_holds_by_org_unit_weight
circ.staff_client.actor_on_checkout
format.time
gui.disable_local_save_columns
notice.telephony.callfile_lines
print.custom_js_file
ui.cat.volume_copy_editor.horizontal
ui.circ.patron_summary.horizontal
ui.general.button_bar
ui.general.hotkeyset
ui.hide_copy_editor_fields
ui.patron.edit.aua.county.show
ui.patron_search.result_cap
ui.unified_volume_copy_editor
url.remote_column_settings

And the following settings are only referenced in a perl live test (to my knowledge):

cat.spine.line.height
cat.spine.line.margin
cat.spine.line.width
