My user community is consistently confused by certain non-standard UI choices
-- white on white Action buttons that don't stand out ... btn-outline-primary btn-sm would be much easier to spot with say a light blue background
-- Note that sometimes you do color buttons to make them clearer ... e.g. Apply on search terms
-- it says Public View in Admin View. I realize it is a menu choice but my users see it as a title since is it separated from the menu bar. It would be much clearer if the top left explicitly said Admin View
instead of just the Wild Apricot logo

In general it's a lot easier to discuss things with users over the phone when the base identifiers stand out so they easily spot them
