While the return codes are very usefull and could be used to offer simular functionality, I scenceerly believe that feature to be able to issue a CLI command after certan operations complete offer better value for the less then script savey users.
Perhaps if some other users post there opinions on this feature request Lightning UK might take it on.
I know I am not the only one who thinks that the ability to issue a command line when Imgburn begins a Queue, Burn Success and Burn Fail, and finish Queue, usefull.
Other users might wish to use a command line text message program to send a text message to there phone or email that a burn or queue job is done.
Don't get me wrong Mmalves, having the ability to access the errorlevels is very usefull for batch programing. But Imgburn already has a great Queue system wich is more accessable to more users.
