Request for documentation improvement. The documentation for the configuration file .jwmrc should include instructions for how to discover the value of WM_CLASS for a window group or application.
Rationale: values for WM_CLASS are non-intuitive, and hence difficult to guess correctly. The values can't be found from the .desktop files. The trick for revealing the values using xprop is obscure.
