I am very happy to have this tool ( THANK YOU
I did want to note that it appeared to introduce some aliasing in a test image I was trying out regarding how it would do with glass.
Adding preserve detail a bit might help.
Otherwise if you have hot pixels in different "Layers" - for example - Separate white pixels could be considered as one and more dense but not white (noise like) fireflies as second, removing each layer in different pass (processing two times) might produce cleaner result (or worse depending on situation and settings).
For example - for bright "layer" you can use low "remove" setting, and high "preserve" setting for another.
Hope this helps, because my working machine is out of reach for almost a month.
Wow! Great job, man! It works fine, but sometimes it leaves some adjacent hot pixels (see animated gif - open it in new window). I'm not complaining - it's useful tool anyway
You can run filtering a second time. Though adjacent pixels are a problem because it's difficult to separate them from needed details. Otherwise lowering "preserve" setting might work.
