I would like to see a feature to be able to test a digital certificate. There is a tool which checks if the software is installed correctly. In almost every situation where I have had to manage digital certificate issues, this test is passed okay and the issue is something else.
I had a new user where we spent hours trying to crack "There is no digital certificate" when trying to sign to discover there was a middle name missing in the profile. Of course, this all happens when we have a settlement looming.
It would be helpful if there was a test in the platform that requires digital signing that could be used ... well ...for exactly that purpose. To test digital certificates and make sure they are all good and problems resolved, PIN works fine, etc before the user is engaged to digitally sign a live transaction - more often than not under some pressure regarding time constraints.
