Is it possible to add a timestamp when a metadata is changing?

You can def do this with the MetaEdit API.

I did something similar and explained it in this post, hope this might help you out :slight_smile:

What I did is basically add a :white_check_mark: emoji to my frontmatter habits to finish them off in my daily notes using a button (buttons plugin)

Because I want it clean and automatically with buttons since you can create them anywhere, there’s quite a lot to it.
