About this Add-on
You can also create a countdown timer through mode/countdown in the menu.
In version 1.5 you can set the countdown timer using a decimal notation. 12.34 will set the timer with 12 hours and 34 minutes. There's nothing to set the seconds, as I didn't think it's needed. To set it to minutes only you can use the short way: .02 - this will set the minutes to 2.
Max count up to 24hrs
