Hello schiberis,

This was all written with Legacy syntax, almost like an AI wrote it for you. But I’m sure you didn’t use an AI to help others, so I won’t ask.

While this will probably work for now, future changes might be a problem and it is confusing for new user software to be written in this form, I suggest changing it to the modern syntax to prevent problems. Or don’t, your choice.

I like this idea and plan to use it, so thanks for the effort. I will be tweaking my copy to the modern format, one way or the other.

Could you give support for critical alert and repeating after some time?
