When the model JSON file is very long, it is extremely hard to locate the errors as it is very hard to scroll and see where the errors are marked.
In addition to have one model file (which can be a huge one), it would be nice to have a functionality to upload one separate JSON file for each TYPE. Right now, from the Left Menu, we can create SLOT_TYPES and add items one by one; so, under each SLOT_TYPE, in addition to add items one by one in the UI, we can have an upload JSON functionality to upload the entire list once. This way for people like me who have one huge file, we can at least split it to a couple of smaller JSON files... So, imagine having a code editor under each SLOT TYPES... Also, the same with INTENT; data of each Intent can be uploaded by a separate JSON...
