The icon for an application stays up on the dock even after uninstalling. I had installed the Pantheon File Manager and placed it on the dock but after I uninstalled it through the App Center, the icon stayed up for about 90 seconds before going away. In that time, it was decreasing and increasing in transparency till it finally went away. Is it possible to reduce that time to a more conservative period?
