Searchanise Search & Filter

I have been using Searchanise Smart Search for more than 6 months now. And it has been functioning well for us. Our users especially benefit from instant search suggestions and results. I believe one small improvement will make it more useful for us. In the search results page, for filters, please provide an option to not include new collections by default. We want to manually add only those collections that make sense for filtering / faceted search. Currently, all new collections are automatically added and we need to go and remove manually. This makes it cumbersome for us. What I am asking for is to provide a switch that disables the automatic addition of collections to the filters, by default. All in all, it is a highly reliable app!
