Digitally Sign - Add preview when drawing rectangle
When using the Digitally Sign tool the first step is to blindly draw a rectangle to indicate where to place the signature. Unfortunately the user is not given an indication of what the signature will look like until after the document is signed. Signatures solely composed of "Text" will have the text fit into whatever rectangular shape that was drawn (which is usually ok); however, signatures composed of "Images" will shrink the image to maintain it's aspect ratio and then center the image in the rectangle, this results in smaller signatures offset to the right from the insertion point. This often returns unacceptable results.
I suggest that the tool to should use a workflow similar to the "Sign" tool. The user is presented with the stored Digital Signature "Appearance" options. The user chooses the "Appearance" and then is prompted to place and scale the visible signature with a preview. Afterwards the user progresses through the options of Locking and entering Pin/password.
