Hey Alton,
I'm sorry for the late reply for some reason I missed your question.
Hotspots 3 will be able to show all hotspots at the same time - Actually you will be able to configure the exact start categories. Here a screenshot:

I'm still polishing things up because it doesn't work to my satisfaction.
As for the static map -> the problem is most probably that you have too many hotspots and the url to create the static map gets too big. That is why the request to google brakes. I'm still not sure how to properly solve this problem, but I'll come up with a solution.
Regards,
Daniel
