Yes - that would definitely be nice. Could I ask you to add it to the
tracker, so we remember it when we have put out 2.1?

I am working on "soft overlapping" blocks in the sharpen/denoise, which
should help significantly in strong denoising scenarios combined with
sharpen. Right now you can experience blocking, which is course is very
annoying. I am about half way done, and with some fine tuning it should be
put in.

Some more information here:

I will also expermient on "limiting" sharpening, which should help avoid
halos around sharpened objects. It basically limits the current pixel to a
minimum/maximum of the original pixels in a 3x3 or 5x5 area around the
current pixel.

Again, this is inspired by an Avisynth filter. More information here:
