--- Comment #3 from rgcjonas@gmail.com 2013-05-28 07:58:09 CDT --- The same problem microsoft was facing when they introduced windows 7. They developed a solution (AppUserModelIDs) which maps quite cleanly to the linux solution (WMClass). We just need to implement that AppUserModelID stuff and export it as WM Classes.
