RT3 overlay issues and requests

Just updated to RT3 and I am not able to mark a roast to be used as an overlay. When I hover over the button I get a not available symbol. This was working I think when I first installed yesterday, but it’s not working today when I roasted.

Update: I quit and restarted and now it is available. What I would like is to be able to add an overlay after starting a roast - is that possible? I’m done roasting for the day now.

Also, I’d like to be able to view multiple prior roasts in overlay mode (two roasts at once). Again, I thought this was possible before but overlay requires an active roast.

Finally, I’d like to have the name of the overlay displayed on the side bar when it is visible.
