In Convertkit, I am able to hover any tags that a subscriber have and I can see when he was tagged with that.

This is very useful for a number of usecases - for example I can see the date when someone has bought something from me.

This is crucial data to know when it comes to marketing, and is useful across a wide variety of use cases as we can add tags for many different things.

Right now if I want to know this data, I have to go into the audit logs which is an extremely unintuitive way to do things.

I have attached a screenshot of how it is like in Convertkit, this is a standard feature for most ESPs / CRMs. I think it should be fairly easy to implement and will be an amazing value add. Best case, we can even add this for "Offers" as well.
