Currently, the "Next" button displayed to a user signing a document cycles through all fillable fields, even if they've been filled already. For a document with a lot of fields with say, 1 required field still missing, the "Next" button is not so helpful in identifying that field.

For example, a document has 100 required fillable fields. 99/100 are filled. Pressing the "Next" button will cycle through all 100 fields instead of isolating the 1 field the signer missed.

Make the "Next" button cycle through only required but blank fields.
