[Feature Request] Display customer signature on quote/invoices

[bit-bat]

When a customer signs an invoice or quote (using finger or stylus), that signature is not visible anywhere in the system. It would be useful if the signature (with date and price) shows up on approved quote or paid invoice.

This can also help make quotes legally binding.

I agree this would be useful.

You can currently see the signature by hovering over the person icon next to the contact name on the edit invoice page.
