What do you use to tell stories for your Sims?

A "screenshot storage" folder on my computer, outside of the Sims 4 folder to eliminate lag, broken out into subfolders for each save/story and sometimes more subfolders by household or by week if I'm planning to write the story down on the forum.

Sadly my Mac's Finder file manager and built-in Preview image viewing/editing app are far superior to Sims 4's screenshot manager. I need to be able to easily rename, batch delete, batch move, crop, reduce image size of a large group of images to aid in forum display, and move around subfolders quickly (or have a good tagging and search system if no subfolders). A shame because I actually like the built-in memory system on Sims 4 where sims can reminisce about certain memories, but it's too hard to find anything in that screenshot manager.
