Description

I wrote some important text and poweroff my machine - to the next day I not found this added text.

Maybe you will need to call SAVE function when system start to power off? Or maybe you can add option to the preferences to adjust the saving time interval or maybe you can save content for every changes?

This is important problem - software for saving content can not save the content.
