Let's say a document is sent for approval. When an approver reviews the document, as the document is in "Waiting for approval" status, the variables are not highlighted in yellow anymore and because of that the approver can't see what variables were filled in by the document sender and which variables were NOT filled in by the documents sender. The client wants a better experience and requests the ability to highlight required variables in such a way that this highlighting persists for the documents in the "Waiting for approval" status. This will give an approver an opportunity to see if the mandatory variables were filled in by the document sender. In my opinion, the color of the highlighting for required variables must differ from default variables highlighting color (we can make them red , for example, like required fields)
