Feature description

I would like the application to support some elements of rich text editing:

• Bold
• Underline
• Italic
• Font size

Optional:

• Font color
• Strikethrough

Those elements would be lost when exporting notes to txt, but they could be used within the application.

I personally wouldn't care for font families (especially since monospace is already an option) and could definitely live with font sizes limited to 3 to 5 choices.

Why do you want this feature?

This would greatly improve the UX by allowing you to give a bit more of structure to the notes
