Back in 2015, @copperdogma rewrote the PHB Index. GitHub - copperdogma/dnd-phb-5e-index: Dungeons & Dragons 5th Edition Revised IndexI don't know if it really "wastes" time - but about every other session there is a point where some rule comes up we have not dealt with yet or often but that seems like it might - so I insist on looking it up - but the 5E PHB index is SO FRIGGIN' TERRIBLE I struggle to find it. Seriously, I get mad whenever I look at that index.
They've done a bunch of new indexes now. May this help you.
