Perfect idea to gain some time!

I love this idea! This could especially be useful for a game or application that has a lot of different types/classes with primitive type properties and you don't want to manually create forms for every single one of them.

Ooooh... My favorite way to customize UI via services! You can retroactively keep all your games up-to-date with security requirements of your services without having to change the applications themselves. Might not resonate with everyone, but I can see how this could be extremely helpful for online games or apps or just with folks who love JSON or are using another tool to define their fields.

This will probably work very well with the MaxSizeContainer plugin for making non-game and web applications.

Very nice.  I've been doing some application development in Godot.  This will be very helpful

I really like the idea! Looking forward to the validation feature.

Simple but nice. An in-editor form editor would be cool tho, instead of writing a json file.
