We are wondering about the possibility of having support for comb fields added into the plugin, or a similar formatting options.
Combed fields are used to create a sequence of boxes that automatically space out each letter of text that is being filled in. These type of square boxes are common in many US government forms and healthcare forms. It can also be very helpful when filling in information like credit card numbers on invoices to make sure items are spaced out correctly. When changing a text field to a comb field in Acrobat you select how many boxes you want and the field will automatically space out each box based on that number.
