It is intended to keep various records, and first of all - cataloged.
It's easy to use: add or select a new category (for example, "My unexpected situations"), and add the record itself (for example, "Was a participant in a car accident"), and write down all the details in the main field. Naturally, the use of this notebook is more universal. For example, you can catalog entries on any topic, or create interpretations for half-sums or sensitive points.
Also in this window you can search for records, change the font, and output records to the printer.
Manipulations with directories and records can be done from the context menu of the corresponding windows.
Records are saved automatically when you exit notepad, or when you change the directory. But there is also a "Save" button that allows you to force save the current record.
