GNOME 48 introduced built-in break reminders support with hidden configure options to protect eyes from strain.
Hidden options include countdown timer, delay seconds, custom break duration, screen fade, interval, lock screen, notifications, and sound alerts.
You can configure these options using Dconf Editor graphically or through gsettings commands in the terminal.
Dconf Editor allows for easy configuration of parameters like time interval, duration, lock screen, etc. while gsettings commands enable command-line or scripting option.
