I suggest that you remove the "arg0", "arg1" parameters from the parameter popup. If the source code is mounted the correct names are used and the names are very helpful. However, the generic schematic "arg0,1,2" and so on only clutters and confuses. (float, String) looks cleaner and conveys the fact that the names is unknown better than: (float arg0, String arg1)
Good idea. See also issue 123913 which suggests including a link to explain how to resolve the problem.
