[Feature request] Center "slide" contents

[thecountoftuscany]

Thanks for the amazing package! Could it be possible to introduce a variable to center all content in a "slide" only in org-tree-slide-mode?

It could be possible by executing center-region in each slide excluding org headings, but I think it is difficult to restore the original position of each content. I'll study how to implement it. Another way to set the content to center in a slide is to use olivetti.el. Anyway I'll study this topic. Thanks.
