Offer an "Import everything" button to the user

A good idea. Would add "Execute all migrations in the suggested order ( ... ) " as a helper description text under the button. Thank you! +1

That's great news, thanks @hongpong!

A helper text like the one you suggested would work great.

I ran into a minor problem while trying to document a complete process in DDEV in How to generate WordPress content and import into Drupal → , and added an issue (have to run drush migrate:import --all twice). Making the "Import everything" button here will probably also fix that challenge with drush migrate:import --all, by correcting the requirements between the migrations, and getting the right order of the process set in stone, to get the button working.

Thank you, it's a great idea. IMO having as much logic outside of the drush file, but called from the drush file, would be an excellent way to achieve both of these.
