I created a launcher on the desktop by right-clicking and selecting "Add Launcher...". After creating it, I right-clicked the launcher and set a custom icon.
When I drag this launcher to the dash, an item appears but with a gray "?" question mark instead of the icon. See attached screenshot. The dash should use the icon from the launcher instead of displaying a question mark.
I don't see any way to change the question mark in the dash to something else (does this feature exist?).
