Yeah, I think that fixing Rogues and Monks, 3 action economy, four spell lists, shortened skill list, Perception divorced from skills (like Concentration was), degrees of success beyond pass/fail, cantrips that scale with levels, monster/NPC design that's more elegant and divorced from player rules unlike the byzantine scaffolding PF1 has now - are all the small changes PF1 needs to be a game of my dreams.
