Discovered this little gem ( well it may not be a gem to you if you knew it already) then when I have made a book of several pages in the iOS app Book Creator it was awkward to move pages around. In fact at first I deleted the page and added a new page. No, no, no. All I needed to do was hold my finger down on the page I wish to move, wait, till it enlarges slightly, then move it along to the position I would like to be in. Simples!
