hide when no parameter in URL

Thank you for this great plugin.

Currently content only shows when a condition is met. However I would like to hide content when a condition is met.

For example I don’t want some content displaying if there is no paramter in the URL – is this possible ?

Also a hide when parameter present would also be useful otherwise I will have to use conditional PHP.
