Hello Tom,
Regarding singular/plural names. The option you found in configuration serves only for GUI in association wizards, where you can configure whether to generate singular or plural form for aliases.

Based on our previous conversations I suppose you're asking for Laravel, right? Because only Laravel currently has built-in feature to generate plural table names. If so, there is currently no way how to turn it off.
Can I ask why is why exactly is necessary to export Laravel tables in singular form? Or what kind of "singular/plural" option are you looking for?
Regarding entity/field ORM properties, it would be great if you can send more details about your project. Is it still Laravel? Because Laravel field has a lot of options as you can see here:

Are you sure you have selected the correct ORM framework? Didn't you choose "Without ORM" project? Can you share your project with me?
I'm trying to build ERDs for Doctrine 2 & No Framework. I'll be happy to send a video to
show you all these problems. It feels like my installation is broken so I uninstalled and
reinstalled but that didn't fix it.
It definitely seems like broken installation of wrong project settings. Can you please send this project to [email protected] so we can check it?
If possible, can you also create video screencast with these missing options?
Thanks
