Bartender - A macOS Menu Bar Utility Bookmark

Bartender is a small macOS app that‘s “giving you total control over your menu bar items, what's displayed, and when, with menu bar items only showing when you need them.

Quite a nice idea, and especially convenient when you have a lot of items in the menu bar which clash with the application menus.

One of the options is the bartender bar, to reveal and display hidden menu bar items.
