Spectrum editor

Were there any improvements in the spectrum editor in Wavelab 7, 8, 8.5, and 9? (I’m still on Wavelab 6 here)

Wavelab 9: Switch to M-S mode and edit only M or only S within the spectrum editor if you like… This is very cool… Someone bump a mic while recording? If it’s panned mono, remove the sound from a stereo mix with minimum effect on anything that is not mono… I’m sure you can imagine the creative possibilities.

As far as any other changes to it, I’m not sure - maybe PG or others here can help.

M/S spectrum editing is the only change in the spectrum editor, since WaveLab 6.
