To keep track of many tray icons you may hide those that you don t need all the time. You can still access such hidden tray icons in the context menu of 12-Tray.
12-Tray will also restore tray icons after a crash or restart of the taskbar (which in fact is displayed by the module explorer.exe, aka Windows shell). Usually the taskbar comes up after a crash without any tray icons. You had to stop and restart all related programs to restore the tray icons. Now, 12-Tray will restore tray icons automatically.
