Enanche the smooth and invert experience

Hi all

My idea is very simple and it aims to overcome the lack of physical keyboard shortcuts.
At the moment you have to distract from sculpting to be sure to click the correct buttons on the sidebar, which is not ideal during the sculpting process especially think that smooth and invert are the two most used features.
So the point is to create 2 virtual areas to access two very basic but needed features such a the smooth and the invert brush.
By having to big areas allocated for the 2 features, I think it would improve a lot the sculpting experience.
Thank you
