Mauer Themes › Support › Storyteller › More Post and Categories
I don’t know if this part of the support policy but is there a way to make the More Post section display relevant posts based on category instead of just recency?
This option is scheduled for the next theme update.
In the meantime I have emailed you two files that you can replace in your theme folder to have related posts displayed based on category (that’s a beta).
Hope that helps.
