I was hoping to find the following feature:
Set an automatic pc shutdown or program shutdown to occur when downloads/uploads are finished.

Would come in very handy when you want something do keep on downloading/uploading while you yourself are out of the house or asleep or doing anything else.
Does Tixati have this?

Right click on the Transfers Button or the Tray Icon, you will find Auto-Shutdown menu Item

You can also use the Scheduler to schedule Auto-Shutdown
