Legacy Apps Sound track pro spectral editing

I had a look at the Spectral Editing in Soundtrack Pro 2.
It's a bit of a joke I find. Not really serious.

Ok it looks great but it's unusable.
There's no way of controlling the editing not even the strength of removal when using the only available editing feature - delete.

Are there any improvements in SP3?
I don't think the spectral view is intended to be a graphical/bitmap editor, just another way of visualizing the data with the same level of control you get in the normal waveform view (normal methods of applying effects and etc.)
