** Opening the note editor having spell activated or activating the spell within the note editor blocks Python / the application for a while (as longer as larger the text). Therefore it's suggested to deactivate the spell checker in Preferences. But it's the same if one toggles this feature or changes the spell language interactive using the right mouse context menu in the Note Editor.

** The spell settings will not be stored.

* The Graphics view and other gtk parts may generate warnings without any other known effect
