How do I remove paragraph styles in Sparkle?
If the style isn’t used and you hover over its label, as well as the edit name icon, a little cross will appear to the right of the edit name icon.
I had an issue where this delete icon would not appear, even though I knew the style was not used anywhere in the document. In the end I found a solution with a happy accident. I renamed the style as ‘unused’ and it seems renaming it disconnected it from the document and the little icon appeared so I could delete it.
