I also dislike the heavily surfaced impasto look that palette knife adds with higher paint loading (but paint roller doesn't at any setting), so it is a good workaround, but it needs other steps to tone the paint texture down later on.

I'm just glad someone voiced they would prefer some more extra settings for this tool and I hope the developers see it and give us something, because I tend to use the tools that are already there to the max, until I realize there might be an easier way to get same look with some effort from the developer.

this thread is an opportunity for as to ask for some extra TLC for the otherwise great palette knife tool.
