I wrote that less than a week ago, and now that script is a proper plugin. It's so hot off the press it isn't in the Obsidian UI yet, but I'm looking forward to when it is (which will hopefully resolve some weirdness I had with the script version).
Current Use Cases I'm Investigating for it:
Interstitial Journaling (super helpful thus far)
Changelog at the bottom of any notes files (need to toy with it a bit more)
Both are good for the “capturing a quick thought from anywhere in a timely manner” case.
