Very often, when comparing spectra with different references, a snapshot function is needed. It would be very convenient if you introduced this feature in the next Cubase update. This is very conveniently implemented in iZotope Ozone 5 in the EQ / spectrum analyzer module. I really like SuperVision: Spectrum Curve, but the snapshot feature is sorely lacking. That’s the only reason I still use the Ozone 5 features for everyday tasks.
+1 (definitely would be a major upgrade for me as well)
