A lot of web UIs only show a refresh button if something goes wrong. I think this makes a lot of sense, as it is really just a placebo if the app already knows that the data is up to date (for example, if it has an active websocket connection for maintaining state). Of course, it helps that the browsers all have builtin refresh buttons too.
