I’ll make this possible in the next version of the theme. Just added it in. But unfortunately it’s outside of the hands of our beloved FILO plugin.
In your Child theme’s functions.php, if you want to place the latest version I have for the mini post list’s function before the framework gets included, it should all work right with how the theme is setup now. The changes made should allow the FILO plugin to just do its thing on the mini post list.
