The user interface (`/if/user/`) embeds a downsized flow executor to allow the user to configure their profile using custom stages and prompts.
This executor only supports [**prompt**](../stages/prompt/) stages. If the configured flow contains another stage, a button will be shown to open the default executor.
Because the stages in a flow can change during it execution, this executor will redirect the user to the default interface _if_ a non-supported stage is returned.
