We'll release a package called docz-ui, that will have a lot of components to help you to build your custom theme (eg. our playground, custom menus, etc).
Don't mind me asking, but is there any progress on this? Creating a custom theme whilst still harnessing the features the default theme offers is now pretty difficult and thus switching themes is sort of a no-go :)

this would enable having docz components inside other tools like gatsby
