App Performance Analytics

In the data editor, it would be great to have an indication of the relative contribution of various parts of the app on the load time or performance.

E.g. A breakdown that allows us to quickly narrow down which table(s) are slowing an app down. Bonus points for narrowing it down to columns.

This would be particularly helpful for more complex apps and help users learn what sort of practices to avoid.

Would this type of feature be possible?
