Good morning. My name is David and I would like to ask the programmers this: why don't you update the software by increasing it with a sound (perhaps configurable and activateable) that plays when a join is completed? I don't spend the entire time with the MP4 Joiner screen in front of my eyes and I would save a lot of time if I had something that notifies me when the joining of files is complete. Thank you and have a nice day. David
