Additional Notes

Notes:

1. This would work really well with #421 or #420. So when the user hits "Edit code" they're able to bring it up.
2. It seems like we'll want to implement this on the left panel, but it doesn't feel completely deserving of a full panel tab in of itself because there just aren't many properties for most objects. @Kitenite we should discuss the design / feel of where this should go a bit.
3. No functionality to add properties, but perhaps we make that a button that just sets up a prompt in the chat saying "Add a property to this component that does..."

I think this could be deserving of a left tab depending on the element. But what about right tab or a subsection of style tab? This will be very useful for components + regular HTML tags
