This issue includes a number of padding changes to increase the readability of a single row and ensures that elements belonging together actually are seen as such:

• move the icons closer to the text
• make the gap between the icons and the arrows in trees smaller, but make sure that the touch target of the arrows remains large enough.
• finally, increase the gap between the check box and the arrow (in trees) or the icon (in lists), so that the two are better separated.
