 - `FEATURE_SIMULATE_SEARCH_LATENCY`: DO NOT SET IN PRODUCTION. Set to ensure a minimum of a one second delay in returning search results. Useful to see spinners/loaders. Only introduces delay for results that take less than one second to complete.
-- `FEATURE_TAB_TIMDEX_ALL`: Display a tab for displaying the combined TIMDEX data
-- `FEATURE_TAB_TIMDEX_ALMA`: Display a tab for displaying Alma data from TIMDEX
+- `FEATURE_TAB_PRIMO_ALL`: Display a tab for displaying the combined Primo data (CDI + Alma)
+- `FEATURE_TAB_TIMDEX_ALL`: Display a tab for displaying the combined TIMDEX data. `TIMDEX_INDEX` affects which data appears in this tab.
+- `FEATURE_TAB_TIMDEX_ALMA`: Display a tab for displaying Alma data from TIMDEX. `TIMDEX_INDEX` must include `Alma` data or no results will return.
