Wazaterm is designed for sustainability. After 2 hours of idle time with no input operation, Terminal will suspend automatically. I would like to avoid unnecessary CO2 emission. If you want to extend the idle time for background jobs, put the .waza_suspend file under your home directory. You can specify the minutes in the file.
$ cat $HOME/.waza_suspend 150
In this example, if there is no input for 150 minutes (2.5 hours), the terminal will automatically suspend.
