I've bought the digital edition to use it during the play on Skype and it seems that it's lacking an interactive table of contents which makes it useless to me. This is not stated anywhere on the page so it's not obvious until you open the PDF you've bought. Consulting the Chaosium support, I've found that they do not plan to add this feature in the future. What's the point in a 300-page digital edition rulebook you cannot quickly browse through?
