Why do I get hideous backgrounds on my widgets created through ExtShortCut, but I don't see the same on your picture?

I note some others throughout the thread have them, but they are absent from your picture. Is it a case of finding an appropriate image for the shortcut?

<EDIT> Ignore me, I'm an idiot. Should have updated first.

<EDIT-2> Seem to have lost the ability to launch via command. Just have the Application or URL option. Is this right? I ask because I was using an ExtShortCut widget to launch the app-search-app script as the original widget it was based on (app-search-widget) appears not to support image resizing of its icon.
