The empty layers are where you make "changes" to the character sheet as you go along. What you do is import a sheet into a layer, and then leave the layer above it empty. This means you can have a 3 page character sheet basically. In the case of Sketchbook, it allows 6 layers. The program in question has layers, which is of course the key. One possibility around this would be to do the character sheet(s) in a drawing program. You wind up with a non-editable sheet, but it does include the text that you entered into the fields.
#PRINTING FROM GOODREADER APP PDF#
In order to get it to show up with information filled in, I've had to "print" the sheet through the pdf virtual printer. If you try importing a form-fillable character sheet into Good Reader, all you get is a blank sheet. The main reason it's a problem (for me) is of course character sheets. But you can't modify the data once it's on the ipad. I mean, you can load 'em on sure, no problem. Only thing that is truly missing is the ability to handle form-fillable pdfs. So in a couple of cases I've taken pdfs that have already had native (in pdf) bookmarking done and added my own personal bookmarks on top of that to get to specific bits I frequently have to reference in a text. Sidenote: A nifty feature of Good reader is the ability to add your own bookmarks. So far, I've found Goodreader to be pretty good.

For windows there's a couple of free options that will set up a pdf printer as a virtual printer, but I don't know about macs. Since I don't have a mac myself, what I've had to do before (instead of the usual "open the file in Preview", with the assumption being that you've got a mac if you have an iPad) is use a virtual print driver and "reprint" the pdf. Layers in pdfs present a problem for a number of different programs (Foxit PDF reader being another one.)
