KeystoneUtils

KeystoneUtils adds utility coverage to the Premade Group Finder tooltip so
  you can tell what a Mythic+ group is bringing before you even apply.

  Hover any M+ listing and you get two extra sections:

    Dungeon Needs
      The utilities that actually matter for the dungeon being run.
      Green means covered, red "missing" means nobody in the group brings it.

    Group Utilities
      Every relevant utility the group has, with who provides it
      (Bloodlust, Battle Rez, dispels, purges, immunities, enrage/bleed
      removal, etc).

  There is also a small addition to the Mythic+ dungeon selector
  (the keystone window). Hovering a dungeon icon shows the utilities
  recommended for that specific dungeon, so you know what to look for
  when building or joining a group.
