Script Version Control

[#1]

I'd love to see more robust script management.  Ideally I'd like to see the ability to officially version or rev scripts.  In addition to the Save button, you could add a button for Version.  This would store the script in its current state with the appropriate verison number.  

In addition, I'd like to review previous versions of the script and have the option of making a previous version the current version.

YES, YES, and YES!!! I love this idea!
