I'm having a slight problem with using this plugin to track Matomo visits across subdomains.
The Flarum install is in a subdoman and I want to track visits across both it and the main domain, which would mean that I need the cookie domain to be *.maindomain.com - I don't see any option to do that here, as the plugin automatically sets the cookie domain to be *.subdomain.maindomain.com and there is no way to specify a different cookie domain.
This would be a really good inclusion I think because I'm sure there are far more people who install Flarum in a subdomain than the other way around.
