Go to Settings > Kitchen Settings > Configuration in the admin left menu (URL /admin/configclient). At the top of the page you will see colour-coded section strips: Business, Marketing, Order, Theme and Other. Each strip contains tabs (for example Theme > General, Kitchen, Navigation, View Menu; Marketing > Analytics, Credit Packages, Giftcards, Hub, Popup, Social, Newsletter Popup). Each tab shows a small pill with the number of settings it contains. Click a tab to reveal a two-column table (Key = the setting label, Value = the current value) and use the search box above the table to filter by keyword.
