I do not agree with “expose top errors” for V1. Provide a link to detail logs somewhere reasonable, sure, but I am not sure we want that much visibility to error logs, it kind of feels like “you as an admin are now also responsible for helping us to debug Discourse” when all they want to do is run their discussions.
If people want to do that, fine, but do not force it into their to do list. Outside of hopefully rare troubleshooting you shouldn’t need to be going here that much, it is like having a “top 3 injuries that sent you to the hospital” page. Ummm.. yay?
