A new button called "Settings" offers the possbility to change the tool palette opacity & color, the category and item height & width can be adjusted, the number of icons per columns can be set from 1 to 4, the icons can be reorganized with a drag & drop, and you can remove some icons by tapping the top-right red cross which appear with a long right-click on the palette.
