Currently if a facet is not shown either because there are no products that "match" that facet or by using the Conditional logic, a large amount of white space is left between the facet "groups." You know how clients are. "Could you get rid of that big gap between the filters?" Would be nice if this happened automatically or had some setting to say "reduce white space when facet not shown."

Much of the documentation is written with the assumption that some things are already understood. Much of it could be improved for the "less-than-super-techy" folks. For example, giving examples of when you might use a feature in "real-life" to accomplish a goal would be really useful. When the documentation includes the exact same text as the on-screen help, it's not really that helpful. More screen cast video training would also be helpful. Adoption and use of your product will increase with better documentation and training. I guarantee it.

When using facets in a sidebar for a large retail store, it would be nice to have an easy way to add a label above each set of facet items that is only shown if the facet is shown. This is probably possible with code but would be nice for it to be built in.
