Need to pass additional parameters from openconnect-gui to openconnect

Summary

I can't pass additional parameters from openconnect-gui to openconnect. This is necessary because of a few other "bugs" that are already known to openconnect (openconnect#618 (comment 1409347807) and openconnect#659 (comment 1954685743)). This concerns specifically the following two parameters:

• useragent=Anyconnect
• gnutls-priority="NORMAL:-VERS-ALL:+VERS-TLS1.2:+RSA:+AES-128-CBC:+SHA1" if I don't add the first one, openconnect does not open the browser for verification and if I don't add the second one, I get a Got inappropriate HTTP CONNECT response: HTTP/1.1 401 Unauthorized error message (this has been reported here as well in #400 (closed) )

I am not entirely sure if this should have been a feature request...

Version of the software & operating system

1.6.2-dirty (64 bit) Windows 10

Steps to reproduce

• Start openconnect-gui
• edit Profile
• severely miss the option to add additional parameters

Actual results

I am not able to add additional parameters to the configuration of a profile

Expected results

I would like to be able to add additional parameters per profile
