[IMPLEMENTED] Custom editor - accessing other fields

Hi, I’m trying to write custom editor by it requires access to the other data fields. Is there a way to get at least read-only access?
For example, I have two fields A and B:
A is a regular string input, and B is a custom. I need to get the value of the A field in the editor of B.

Sure, sounds like a good feature
