I know that there is a feature request to be able to toggle on and off the icons above different island structures, but this isn't that. I just want the icon to no automatically longer display when all of the pirate types in either the academy or the voodoo hut are maxed out in training. In fact, I would even go so far to say that it still showing now is a bug, since there is no training left to do. This feature would make the interface more consistent and correct as, currently the icon disappears whenever the academy or Voodoo hut is under construction for upgrading, meaning that training is not available. The coding and feature are obviously already there in the game, so this should be a relatively small thing to add, out of all the requests out there.
