The ‘hidden slide’ feature is great. It can be used to design a master presentation that contains a couple of versions of key slides – just hide the ones that do not apply to that audience. Or you want to edit a slide, but keep the original for that ‘just in case’ scenario.
No matter what the use, the one constant is that it is difficult to identify which slides are hidden. You have to look for the small hash mark here:
Not only is small, put the is no way to identify hidden slides on a printout. This poses a large problem when supplying printouts to clients for review. What I have done is create a semi-transparent, slide-sized “hidden” graphic in PhotoShop that is inserted on hidden slides. Easy to see in the slide sorter and very obvious in printouts.
