I know the feeling, may it's the spread over several books and/or the almost random organization of those books, but I find whole revelations everytime I open them.A for instance: that find you made on DEX effecting saving throws. Don't remember that in the slightest (though I remember WIS for some reason, strange).
And Magical Armor can effect Saves vs. things like Dragon's Breath. :)
