    Hi, I find the project interesting, however I can't understand it because of the interface, I can't find the functionality to place my signature on the document.

    Works very well! LTV is supported, users need to select "Advanced view" click on: "TSA/OCSP/CRL" and activate "Enable OCSP" and "Enable CRL". Now (v2.2.0) it supports ECC signatures, I tested with NIST P-521, and is working great.
