Pretty simple suggestion; put all of the deity-specific shop items from this month into their own separate section before the universal shop items in the event shop (like how backgrounds have their own separate section from decors in Monkey Business). It would be easier to figure out what's deity-specific or not, and more convenient to find a deity-specific decor you're looking for without having to pick it out of all the universal shop items.

Just a small quality-of-life change I think might be helpful
