sexilog - rename elasticsearch filters?

I've put in sexilog but obviously the name 'sexi' is not appropriate for an enterprise solution. I really, really like the product but I cannot seem to find a way to intutiively manage the filter names sexilog created in elasticsearch. See the image below where the head plugin shows the fitlers but there is no way to I can find to rename or delete

Any ideas?
