# Preview and configure customer account UI extensions in the Checkout and Accounts Editor

As a part of the [Customer Account Extensibility Developer Preview](https://shopify.dev/docs/apps/customer-accounts), you can now add, remove, preview, and reposition customer account UI extensions in new customer account pages, to better understand how merchants configure apps in the checkout and accounts editor.

Included in this update, you can also:

* [Group extensions into collections](https://shopify.dev/docs/apps/build/customer-accounts/editor-extension-collections): Extension collections guide merchants on which extensions work well together by creating collections that help merchants confidently enable your recommended customer experience.
* [Set default placements](https://shopify.dev/docs/apps/structure/app-extensions/configuration): Default placements automatically add an extension to a specified UI block.

[Customer account extensibility](https://shopify.dev/docs/apps/customer-accounts), currently available in developer preview, enables partners to add unique and powerful customizations by building extensions directly into new customer accounts.

Get started by reading our [developer documentation](https://shopify.dev/docs/apps/customer-accounts/extension-collections).
