I know noise gating is very different from noise reduction; however, it would be extremely awesome and helpful if the next version of Pro G comes with de-noising options along with the gating. It would make it a lot more useful, and the combinations of noise gating and de-noising would be endless, and also that would make FabFilter the first company to release a plugin that can handle noise gating and noise reduction simultaneously! I cannot emphasize how useful this would be enough.
Noise that would typically just be gated under a certain amount of dB would now be removed entirely or to a certain level if one desires. One would have the option to use the gating/expanding functions with or without the de-noising, and how much de-noising, and in what specific frequency ranges if they would like etc. De-humming, de-hissing, and such would be possible. A person would have the ability to audition noise in different parts of the spectrum before and after the de-noising has been applied.
I hope you seriously take this into consideration, consider the endless possibilities, and how feasible it would be to make.
