Is there anyway to get the temp/layer info on overlay of the control screen (info on the stream)
You can use my https://github.com/jneilliii/OctoPrint-SideBarTempGraph for displaying the temperature in the sidebar, then it's visible on every tab. I also expanded on one of Gina's proof of concepts that combines the two mentioned tabs on one, https://github.com/jneilliii/OctoPrint-ConsolidateTempControl.
