JSON extensions

Reference to other files: A special tag could be used to refer to a file relative to the current one. It would then be substituted. This mechanism could also be used as "template". The referred file would be loaded first, but the 'calling' file could still specify fields that would override the loaded file.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
