For years we used tmux as the driver for breeze's start-airflow command, however there are better alternatives.

One of the best ones available now which seems to perfectly match our needs is mprocs.

It's a modern alternative to tmux for managing multiple processes. It provides:

  • Intuitive TUI with better visual feedback
  • Easy process management (start, stop, restart)
  • Mouse and keyboard navigation
  • Process status indicators
  • Better cross-platform support

For now you need to use --use-mprocs flag to enable it, but once we test that it works well we can make it default.
(cherry picked from commit b7b4385)
