Any chance you could add some kind of config changed event?

I have a couple of mods that are using Forge Config API Port and I want to switch to using this, but both mods require that I refresh some things, like repopulating a list or refreshing a cache when the config value is changed. Right now that would mean I would have to require the user to restart the game which I'd rather not do.

I'm not very good with kotlin, but if you're ok with it I could try to do it and make a PR when I'm done

This is a feature I am adding to the inDev 0.5.0. There will be an onChangedClient and onChangedServer that will fire once per respective side when the config state is "popped" (typically when the config changes are applied and/or the config screen is closed)

Great! Thanks for letting me know
