On the Maestro, you can click on the lower right corner of the screen and get "METERS" screen with lots of great meters with great information. On the Windows PC version of SMARTSDR I cannot find a way to display this good information. Or did I miss a button?
All of the information that is presented in the Maestro meters, and more, is present in the SmartSDR display, in the stack of sub-panels on the right side of the SmartSDR display and in the Slice Receiver flags. You can turn these sub-panels on and off using the buttons along the top right of the SmartSDR display.
