Thanks for letting me know about the ability to turn off real-time updates in the new betas; I think manual entry boxes might be also worth considering for the future alongside slider widgets like GIMP does.
I use this function for final noise reduction and I could do it in GIMP with its wavelet tool but the interface on GIMP is a bit clunky for this application. I understand Siril is for pre-processing but it does have a few standalone post-processing use cases.
Thanks again
