I set this up a few weeks ago and it's working great so far. You start to develop muscle memory and now i organise everything to the same order, eg bookmarks

i think it's partly that i remember location phsyically. i can remember bookmarks in real books, my remembering where certain words are on a page and flicking through until i find them. i wouldn't stand a chanec ofremembering page number. somehow the JD system recreates thsi for me
