I am using the free version to gather logs from 4 sources.

I need to add custom patterns for one, a Sophos UTM firewall.

I am unable to do so due to "Custom Patterns" being greyed out.

IS this function not available in the free version?

if it is, how do I use it? 

Another thing: I also seem to be unable to customize the dashboard views.

are those problems undocumented limitations of the free version, or am I doing something wrong?

Kind regards,

Frank
