Another option I thought of for the inventory was if we could specify a page to jump to.
When I redecorate my realm, if I change the castle grounds each month, I have total approx 130 for each item I want to get to page 130. It would be nice to specify I want something on page 130 and tap 2 times instead of 130. My hand usually hurts by the end of it because of the rapid small movements. (Example: For December, I had to tap the arrows over 2,600 times.)
