I'm sorry that you feel that way about the plugin. I wish you would have contacted me directly through support instead of posting the review, as the timing may indicate that you're not going to use BD anymore. I take support very seriously with the plugin and aim to make everyone successful with it.
It may interest you to know that the Featured Levels has been a real challenge to get working in a simple way that didn't make the user experience a problem. That's been the major delay on this. We've only advertised it as Coming Soon since early April. My apologies on the delay. I certainly didn't anticipate it taking so long to get right.
But with that said, I'm sure you can appreciate the need to not release software that isn't working well as this would be far worse than making you wait for something that does.
For your other questions, BD is compatible with WP-PageNavi, allowing you to display how many pages of listings you have. We went with that route, since WP-PageNavi is a well-known, stable plugin that people were already using for that feature. Also, the number of listings displayed can be easily changed under Settings->Reading on your site. We use the same setting as your site's posts/pages displayed.
I would welcome a further conversation on the matter if you want: http://businessdirectoryplugin.com/contact/. I do want you to be successful with it.
And just so you know, Featured levels is releasing early next week. I have a version that is available to Combo Pack buyers now, but it requires you to upgrade to BD 3.1 to use it. Same with ZIP search.
