Make default json field to jsoneditor?

looks it is a nice component for edit json.

There is a process for suggesting enhancements to Django. Please read

Or, am I misunderstanding what you’re trying to ask here? Are you trying to figure out how to use this editor in your own project?

I want to make a DEP, but also want some discussion

Ok, so lets jump-start the discussion.

Why should this be brought into core as opposed to adding it as an external package when desired? The bar is set fairly high for new features, since everything new added becomes future maintenance effort.
(Also see Requesting features)

I think it worth. I often hope JSONField in admin more user friendly, I don’t know how many people think as me.

Maybe you are right, it should be a third party library
