Can KA Add Timestamps for JS Program Edits?

Multiple times, I have wondered when I made certain edits or even how old some of my programs are. I cannot find where the timestamps are, and am wondering if they can be added or made more visible. The timestamps can be similar to history timestamps in apps such as Google Docs, in which I can find previous versions of files and older edits, as well as when I first created the documents.

I believe this would be a very helpful feature to add. It is one of those things that I stumble upon all the time and just don't know how to change it! Thank you!
