In the new version we introduced a new editor "Markdown editor".
To change the text formatting, right click inside the sticky note and choose to the option "Switch to Standard editor" so that you can use the old way of formatting that existed in previous versions.
You can also set Standard editor as your default editor using Notezilla
Preferences (Note tab). To access Notezilla
's Preferences, right click on Notezilla
icon and choose Preferences from the menu.
