Filter Forge is in my opinion the best node based texture filter program available. Sometimes things can take a while to render especially at 64 samples but thats not a problem for me.
The visual rendering complete message box is good but some kind of audio notification complete option would be super nice. Any kind of audio notification option would be excellent.
Having to continuously look at a computer monitor waiting for something to render is not allot of fun

but with audio notification myself and others would be able to turn up the computer speakers and go do something else during long rendering periods

.
I'm not sure if this request have already been made, I apologize if it has.
Thanks.
