Hey there, José!
Awesome, thanks for checking out the plugins–we appreciate your support. 🙂
Yes, it is possible to get a unique URL for options that are selected in the Filter Bar and then link directly to the query for those events. In other words, Filter Bar does not allow you to pre-select filters, but you can indeed do a filtered search and then re-use the URL of that search.
Is that what you were looking for, or is there any thing else I can help answer? Please let me know.
Cheers!
Geoff
