#=========SETUP========#
# Select which parts you want active by  #
# commenting them out. For example, on a #
# desktop, disabling the battery message #
# is a good idea. You can also re-order  #
# them to change how they display!       #

randgreeting="off"  #< Turn the random greetings on (eg. "Hello <user>, Hi <user>")
twelvehour="on"     #< Switch between 12 and 24 hour time (eg. 8:00pm vs 20:00)
rechargenotif="off" #< Notify that you should recharge if below 15%
flatpakupd="off"    #< Check for flatpak updates, this slows startup down A LOT

welcome
greeting
clock
battery
updates #< This makes startup slower
