But what is wrong with Graphic EQ and Filter Curve? They are basically the same functionality that existed in the old Equalization, but with the bugs fixed.
The two parts of the old Equalization did not “play nicely” together.
There isn’t really a “they” in community developed software, there’s just those people that contribute and those that don’t.
I assume that you mean the “Click Removal” effect. That has not been changed. I know that effect is rather limited in that there are only certain types of click that it can fix, but as far as I’m aware it isn’t “broken”.
