# Usability improvements

A set of usability improvements, both on the editorial side and on the development side:

-   **custom locales**: you can now add whatever locale you want, just type it out and if it doesn't exist, it will be created for you! No more limits here

-   if you have more than 5 items in a dropdown, we'll let you search in there:
    

(Video content)

-   now also **fields can be duplicated**. This is particularly useful if you have complex fields with lots of validations (say modular blocks, links, etc) that you need to duplicate with some sligth variations
-   last but not least, we've add a new parameter when getting a record: `nested=true`. If you add that, **you'll get the modular blocks inlined in the record response and not as IDs** that then will need another call to retrieve the content. [Read in the documentation](https://www.datocms.com/docs/content-management-api/resources/item/instances.md) all the details and see an example.
