TOPIC: Ctrl-Z

Many times I inadvertently delete a comment, or make a mistake without realizing it.  Unfortunately, the Ctrl-Z command is not active on HIP forcing me to re-enter my data.  I'm thinking it would be very helpful if we had a simple Ctrl-Z command to save us from our clumsy mistakes.  I'm wondering, does anyone else is having the same feeling?  It seems that this would be one small step to a greatly improved program.   

Unfortunately due to all the complex features that HIP has implementing CTRL-Z is actually extremely complicated. That's part of the reason we've built in a ton of safety measures now so that if you do go to delete something, save over something else, etc, HIP will pop up and prompt you to see if you're sure you want to make that action. If there's another place you'd like to see this, let me know.
