DisplayFusion allows you to download scripted functions from an online repo; it'd be great if LogFusion had the same kind of thing.

For example, if I was looking at an nginx log I could search for a rule that highlights 404 errors. If I couldn't find one (404 rule not found hehe), I'd make a new rule and then upload it to the repo for others to use.

+1, this would be a great feature.
