I have been playing this game for years, and I am truely disappointed in the way that the monster sorting is done. It would be so easy to fix this issue as the suggestion that I have should take a good programmer less than 30 minutes to implement this fix.
Add a button that would allow the monsters to be sorted from highest level to lowest level or vice versa.
It's so frustrating to have to scroll for 15 seconds just to get to a single Monster only to have to start over because I looked at where it lived or it's stats.
This is an easy fix prove to me that you even read these and fix it.
