HTTP proxy with FTP supprot

In our network we use Squid (http://www.squid-cache.org/) as proxy server (with authorization). Unfotunatelly we use it also as a proxy for FTP connections, and for this reason I can't use SmartFtp, which i like very much.

Do you plan to include suppport for "HTTP proxies with FTP support" like Squid is in SmartFtp?
