Is it possible to define user-defined formatting characteristics when creating a message and to save them permanently for each new mail created? In particular, I would like to be able to user-define the line spacing at the top and bottom (i.e. the line height ) and, if possible, also the other formatting parameters (such as font, font size, font attrbutes and so on) in different paragraphs and save them permanently for new mails. The existing option ‘Paragraph’ via the menu items Format - Paragraph - Paragraph does not offer this possibility according to my tests. Is there such a possibility in Thunderbird? Many greetings from Germany
