Dozer is a simple application that lets you hide menu bar icons that you may not need all the time. The program has the ability to keep a few icons visible while hiding the unnecessary ones. Once you have hidden your menu bar apps, only the tiny dot icon will be visible. However, you can reveal the hidden icons easily, with just one click on the desired icon.
You can download it from https://github.com/Mortennn/Dozer/releases/tag/v4.0.0
Note: Key combination to move menu items are Command + Drag (using mouse).
