I've built these spreadsheets in a Marketing Operations capacity for my marketing teams and our engineering/product/data science counterparts that helped with implementation. I've also done this agency-side.

I can see some value here as a nice UI around it, particularly if there's various roles and permissions I can set for who does what. Also, props to OP for showing screenshots large enough to see what's actually going on in the product.

I'd echo your suggestion about actual events. These should probably be funnel-related events and not random product activity.

Another thing I'd like to see is some sort of version control and changelog/commit message functionality. Having access to the current events and their context is one thing. Having context around what changed and why is another layer of value that is critical for teams that may not be closely interacting on making these changes.

That's really getting into the workflow aspects which include things like notifications and alerts, as well as piping into analytics tools to monitor for things when an event stops reporting data (which may indicate something broke).

CaveTech, are you aware of any other tools on the market that try to productize this common use of spreadsheets like this?
