Annoyed by too many icons or the spacing of them on the Menu Bar in macOS? Here are a few programs that can help keep them under control.
Hidden Bar, Free
Dozer, Free & Open Source
Vanilla, $10 for Pro
Bartender, $15
The first three work similar to each other, with a basic "collapse" feature to hide icons. Bartender stands out with a bit more features, including its own bar for icons that can be displayed under the menu bar. Great for when you have a lot of icons on a new MacBook Pro that has a notch.
