I want to create several Impress layouts, different from those already provided. For example, with title field in one short column and content in second wide column, or a slide with only text content (no outline text) but no title.
I am not talking about master templates, which are in charge for decorative elements. I am talking about the layouts like those that are in a panel in sidebar, below Properties panel.
Might be a solution to do it with a macro, but I do not know so much about the API of Impress.
