Digital signature feature

Hi,

Does the PDF24 roadmap development includes a feature to allow an easy way, like a button on the main screen, to sign pdf files with a digital signature from several different keystore types like a citizen card reader or token and with these simple steps:

1. select visible or invisible signature;
2. draw the signature area;
3. display activate certificates to select from;
4. apply certificate (also ask for security pin if that's the case);
5. if successfull ask to save new filename suffix, like "-signed"

Should have this features:

• timestamps from authority in signature (TSA)
• certificate validation through CRL and/or OCSP

Best regards
