It recently occured to me that when I scroll through my list of heroes inspecting the list looking for badges to add, mods to apply, skills to upgrade, level XP to add or Friendship Campaigns to play, there is just too many.
And the majority of them I am ignoring because I am simply not using them or it is impractical/impossible to upgrade ALL OF THEM.
So I think a function should be added to hide/unhide heroes individually, so the list diminishes to a more manageable number.
This problem will only get worse over time, because new heroes are constantly added to increase the selection quantity.
