the type coverage checker already has an option to choose gen 6, and abilities that effected resistances have been here from gen 1. I know there are multiple suggestions to add abilities to the type coverage checker but its made for weaknesses and resistances, not every ability. But these effect weaknesses and resistances. Just in case someone thinks there are to little of them: there are 29 pokemon with thick fat, 27 pokemon with flash fire, 28 pokemon with water absorb, 8 pokemon with storm drain and much more...
