When adding Radio Buttons on forms, users need options for "Open Square" and "Open Circle" Button Styles. The inside/middle of the button should be transparent, so that users can easily see the text behind their underlying choice. This would simulate users circling a choice with a pencil/marker rather than completely "filling in" the circle or square.

Additionally, it would be nice to be able to change line color and line thickness of the "open circle" or "open square". Currently, users can only change the border color and line thickness of ALL radio buttons, regardless of whether the button is selected by the user. But I don't want a square or circle border around EVERY radio button choice. I just want a square or circle around the selected choice.

Picture number choices: 1 2 3 4 5. The instructions on the form would instruct users to "Circle the number which matches your choice." If the form is printed by users who prefer to complete the form manually with a pencil or pen, the number choices simply show as numbers (with no border) and a user could simply circle their choice. BUT, if filling out the form within Adobe Acrobat (or Reader), the light blue/gray shading appears over each number which was designed as a radio button. When a user selects the number 3, a circle or square is drawn AROUND the 3. And when the completed form is printed, it prints with a circle or square around the number 3. So it looks almost the same as if a user manually circled the 3.

I would hope that this should be an extremely easy idea to implement, which would be likely appreciated by many users.
