Hi Julian,
thank you for your service!
The problem should be resolved with the update.
Look how it is done in MS-word.
When I press "Shift + Enter" there is no blank line after the heading, but then the following text takes on the formatting of the heading.
That should be changed.
It would be good if you can adding a feature for superscript numbers and letters.
P.S.
Du solltest das Programm auch ins deutsche übersetzen, da der Deutsche ebook-Markt vermutlich der größte in Europa ist
