The "Status" metadata option is useful for looking for completed projects. However the filter option doesnt show in the sidebar unless you have it selected which makes discovering this feature a little obtuse. The only way to select it is to enter the url manually (e.g. https://itch.io/games/released ) or click the status link when viewing the "More details" section on any game.

It would be super useful if this filter option was always visible in the filter sidebar like genre, price, and etc.
