Dec 22nd, 2023: For a long time I've wanted to add a Persistence Spectrum, now I've had the time to do this and see how it enhances SDR Console. This is a powerful tool that allows radio enthusiasts to fine-tune their reception and transmission. With the Persistence Spectrum, users can explore a wide range of frequencies and persistently pursue the perfect signal

So, what is a persistence spectrum? From mathworks.com: The persistence spectrum is a time-frequency view that shows the percentage of the time that a given frequency is present in a signal. The persistence spectrum is a histogram in power-frequency space. The longer a particular frequency persists in a signal as the signal evolves, the higher its time percentage and thus the brighter or "hotter" its color in the display. Use the persistence spectrum to identify signals hidden in other signals.

And there's more good news - the persistence spectrum does not consume significant resources.
