Absolutely, I’ll add a simple warning dialog. However, I’m not entirely sure which relays are the best to use. I’ve included some brief explanations on the relay configuration page, but ultimately users need to configure based on their own needs.
It would be great to have a service like nstart.me that helps users choose the right relays. Also, when users switch relays, it would be ideal if related events could be synchronized from the old relay to the new one.
