I configure the "brushes and tools" toolbar. In which I want to have easy access to the "brush smoothing" sets. Every time krita is restarted these disappear from the toolbar. To fix it I must configure it again, remove them from the "current actions" and re-add them. I asked for help in the forums and the result no matter trying to save and so had the same result as I'm having.
