Hi George,
At the moment no, I’m sorry.
But if you need to filter your regular posts you can make use of WordPress own function http://codex.ww.wp.xz.cn/Function_Reference/wp_dropdown_categories
That will give you a dropdown much like the Beautiful Taxonomy Filters does it (it actually uses a modified version of that function). There is even a few examples of how to create a filter on your own here: http://codex.ww.wp.xz.cn/Function_Reference/wp_dropdown_categories#Examples
There is no clear roadmap of where and when the planned features for this plugin will come as I have to do all of this mostly on my spare time. But I promise you I want to be able to support regular posts just as much as you 🙂
