Understood.
I've actually opted to not use Gridless for this project sadly. I did have a DB oriented solution already that was I was going to replace, but the issues with collection reference made it more difficult than it was worth at the moment.
I REALLY like the tool. The interface is clean and simple, and it's easy to mock out really complicated data in an intuitive way. I think it needs a little more polish for what I need though, so I'll revisit it in the future. Especially if I can keep Gridless in mind as I'm building the schema for my next project. It's not hard to match a new project up to it, but an old project that isn't going to cache everything from a single Json file would require some changes that don't add enough value for the time I'd need to spend.
