Icon Size: Select your desired icon size from the drop-down menu.

Misc Options:

      Tip: Use a border when not using custom images for a more finished look.
Auto-close open groups: Enables or disables automatic closing of menu groups when another group is selected or the user click on the desktop. This setting is written to a file in the theme and controls button operation on a per theme basis.
Don't close main dock: Enables or disables the closing of tiles snapped to the main tile.
Don't close groups not on main dock: Enables or disables the closing of tiles not snapped to the main tile.
Snap Distance: Defines a default snap-to "magnet field" for auto snapping to adjacent tiles.
        Tip: Too large of a distance can cause positioning errors, especially if the snap distance is larger than the tiles being snapped.

Additional Theme Options:

Icon Recolorization:

Allows you to custom color existing icons used on tiles and task tiles to match your theme.  As you enter specific RGB values, you may preview the color change by watching the sample HoverDesk icon.
