I think it would be nice if there was a keyboard shortcut/mechanism for folks that may want story tags added to stories on save (similar to how the folder name is added).
I noticed this topic from ~8 years ago that was a no for a preference: Auto add story tags and bulk load them from currently saved stories
While there is a manual way to do it, I believe it is only a mouse-based flow. I currently go through my feeds keyboard-focused and hit S for save. I would be pretty excited if there was an alternate shortcut to hit for saving + add story tags.
