Show _what_ props change when in debug-mode

[torgeir]

It would be useful if the .debug() options on omniscient and shouldComponentUpdate outputted what props changed, instead of just => true (props have changed).

This would ease fixing stuff like unnescessary renders that happen because of changed passed function references, and help show when you'd benefit from something like omnipotent's ignore

So you are thinking diffing the two states/props? That could work, but should only happen when it has changed.

[torgeir]

Yep, that's where debug log already occurs. Diffing or not, it would be useful to pinpoint the prop that changed, so it's thrown right in your face 👊 We already know something changed, we might as well say what, so there's no need for digging around..

[mikaelbr]

Agreed.
