Pre Sales Question: Date filtering

First of all: Great Plugin already in the Free Version.

Secondly: Is this here the only place to ask presales questions for the PRO? Should be over there on Codecanyon after all, will help your potential clients, not everyone might find his way through your other website to here.

Third and my main question: I hope to have found a way with the help of your plugin to create a calendar for which I already have set a custom post type with the date in a custom field. Now I would like to offer the user the option to filter for dates, in best case selecting a day, a week or a month.
– Is advanced date filtering as such possible with the PRO version?
– If not, is there at least a way to use the range slider in connection with the date and how would this look like for the user? (It should not feel like a patchworked thing but professional).

The reason why I don’t use an existing event plugin is that they all don’t offer more than 2 taxonomy, but I need at least 3 so my own custom post type in connection with your great plugin give me hope to create my own solution.

Thanks in advance
Sofian
