It would be possible in the next update to make some improvements on the icon labels the Shelf?

Suggestions:

1 - Increase the icon vertical spacing for more than 50 pixels.
2 - Add an option to increase the "space" between the label and icon.
3 - To choose the icon of the label will appear above or below when the reserved lines are disabled (explanation in the image).

Note: I do the second request not like the reflection, but without it the icons are very close to the label.
