Yeh in hindsight, I like that it doesn't auto add them.
I am still wondering if there is a way to apply changes in settings to already imported entities. Currently, if i change something (like a name pattern) I am having to remove all the entities and re add them which also has me recreating M2M relationships and any other customisations. Its not a huge deal, but sometime I go ahead and start customising my entities adn then realise I forgot to set the name patterns. Then i sigh and do it all over again.
I would suggest these make better defaults:
OneManytoOne - {$EndEntityName}Using{$StartEntityFieldNames}
and
OneToMany - {$EndEntityName}Using{$EndEntityFieldNames}
Beats ending up with "User", "User", "User_" which lacks meaning.
