Twice is a macOS menu bar manager for hiding, showing, and arranging menu bar items.
Twice is a fork of Ice by Jordan Baird (buy him a coffee). The original appears to be abandoned and was failing on newer macOS releases, so I made some fixes because I wanted to keep using it. No guarantees about its future, but for now, it works.
Download the "Twice.zip" file from the latest release and move the unzipped app into your Applications folder.
