When viewing a completed roast, there is a tooltip which follows your mouse with all the temps & settings for that specific point in time. It would be nice if the same was shown when viewing the active roast as well.
For anything after the current time, there wouldn’t be much to show, but it could just show a - or some other placeholder.
It would also be nice if, when an overlay is on, the tooltip also showed the temps & settings for the overlay.
