Cool. I went for the 'quadrant' zoom/pan approach so that I could see more at a glance when I wanted to. I like your index 1, index 2 in the footer. I've also thought of a few ways to improve what I have, but won't have the time for a while to work on it.
One idea I have is to create a tool for creating indexed notepads like this. The user would then supply a PDF template or list of PDF templates that would then be repeated and bundled together with the appropriate hyperlinks. The commandline would be something like this:
pdfnotepad lines.pdf:10 blank.pdf:10 meeting.pdf:10 calendar.pdf:1 info.pdf:1
I think I know how to do it already, I just need a bit time to implement it.
BTW, it looks like you created yours using word. Did you create all the hyperlinks manually, or did you have some way of automating it?
