Support for PDF Text Boxes

When working with PDF documents that include text boxes for reader input (common in forms and study materials), Marginnote currently displays these as underlines rather than interactive input boxes.

This limitation affects users who rely on Marginnote for: 1) Filling out forms; 2) Completing interactive study materials; 3) Annotating certain types of academic or professional documents.

I have to switch to other PDF applications to write directly into these boxes, which disrupts our workflow and reduces Marginnote’s effectiveness as an all-in-one study tool.

Thank you for considering this feature request.
