I have created a master page pair and was able to export and import it into another project. And I realized, that only frames got imported, but no font or paragraf styles – even no alignments of paragraphs.
So I went through the manual, youtube etc. but didn´t find the answer for this question:
Is there a possibility to create something like a »house style« incl. typo, notation options, master page settings, …, save it and import the whole package to a new project?
And: is there a possibility to create different house styles?
