thanks for the latest update - I actually noticed the issue related to too many ads per page, but I figured it'd be specific to my install - so thank you very much for fixing it!
Here's my suggestion:
Given the rather "excessive" set of features already supported by ad-injection, I was wondering if you could add a checkbox that allows automated-pagination of posts?
Your plugin is already internally using all sorts of related settings (i.e. words before ads, paragraph size etc). So it seems your plugin could just as well provide an option to automatically paginate postings using the same set of rules?
While auto-paginations seems to be somewhat controversial, it is also pretty popular:
What do you think?
PS: Obviously, your plugin is very comprehensive and powerful - but its set of features and configuration possibilities can be rather overwhelming, I would suggest to make more use of logically grouped "tabs" for categorizing the settings, possibly using a wizard-based order, so that it is easier for new users to set up everything.
