Hi,
We have researched the possibility of adding the Laravel/Eloquent support several weeks ago. It is not yet on the road-map because as far as we know, this ORM does not use separate definition files nor annotations, therefore we will have to perform larger changes in the ORM Designer. We are open to the idea of Laravel support but we will have to investigate the question in more details first.
We are also looking for an Laravel user/developer willing to assist us with implementing the support. If you want to help us with the testing/veryfying the Laravel support in ORM Designer, it might speed up the process.
For the time being, I will add Laravel to the Roadmap thread as being researched and post all future updates there.
