This looks cool. If I have a log file with a format that is like `[timestamp] SEVERITY { json content }`, can I use the feature that pretty prints the JSON part, or does the whole line need to be valid JSON? If not could I somehow write a plugin that would allow me to parse the lines in order to accomplish this? That would be really useful.
