Well executed! Low fuss. The widget process was intuitive and worked good enough on mobile. Shareable link was easy.

Some minor thoughts: Are the radio buttons meant to have a big outline? Any way to erase the signature? What tech did you use for the frontend?

Thanks! The radio buttons as well as check boxes do show an outline so that they can be used in PDFs where no existing outline exists. If the PDF already has these outlines, the widgets can be resized so that the outlines of the widget match the existing ones.

You can erase existing signatures by overlaying a new signature widget on top of it and specifying a solid color as the background.

The frontend uses React, with Firebase handling most of the backend stuff.
