Bartender 4 - Award-winning app for macOS that superpowers your menu bar

I've been using Bartender for years and, while it was already a must-have, this complete re-write is really slick! The Show for Updates feature is fantastic. I only see Time Machine during a backup and WiFi only when I disconnected from Ethernet saving precious space for required tools!

Simple open source alternative is dozer. https://github.com/Mortennn/Dozer

Great for cleaning up the menu bar space but also great for assigning keyboard shortcuts for thing you can't usually assign.
