it is not a plot to not let you learn about Spriter. Almost everyone use it while they work with Spriter. It is just a matter of alt tabbing to the guide, which is no big deal. Personally I think you are making too much of it.
There is also a variety of very good videos that Mike has uploaded to youtube, I got used those to learn Spriter. Overall, if you are serious about doing art, you need a second screen (monitor or a tablet).
