Well, I can't get anything to attach, so I must be doing it wrong. Anyway off in the right hand corner by the reminders and the x to close, up on the top menu bar, sits a button labeled  Discovery Hub. Inevitably I will click it instead of Reminders and I haven't seen a way to remove it from the bar or hide it or what ever. Please come up with a way to hide it and let me or us if any others want to know, how to take care of it.
