so I just noticed recently that osu! now displays your total playtime by days.. could there be an option to display your playtime by hours? just like in steam
You can hover over the number to display the hours. There is a request for this to change open on GitHub (https://github.com/ppy/osu-web/issues/4558), but it was intentionally changed to its current display with hours on hover a few years ago, so ¯\_(ツ)_/¯
