No problem! And I think the "hold ctrl" prompt was added in a recent update since we had a couple PC bugs where it would crash when retrieving an item from a boxed mon or accidentally using the multi select prompt on an empty slot.
Hello! The first request you mentioned about mass release is already an included feature with the multi-move function I believe unless I'm missing something. Box moving does sound like a nice QoL feature though.
Howdy! In post restoration you can buy the Luck Incense and any other incense at The Emporium in Beryl Ward! It's by the first entrance into the jungle. I can still toss ya a Happiny if you'd prefer though!
