Hi Ahmed,
in a successful CQRS/DDD implementation, front-end most likely will end up following so called Task-based UI approach, where UI is designed in a way that it captures user’s intents and translate them into the commands.
So it depends on how you model the entire system, you could represent the giant form editing as a single command, which will pretty much look like a U from CRUD, or you could try to identify what user really intends to do and decompose this U into further commands (intention revealing actions).
