Is there an official feature request form for Avidemux?
Whats the URL?
If not: Is there an official email address for the developers of Avidemux?

My best guess would be the forum section:
QuoteUser interface and Usability (http://www.avidemux.org/smf/index.php?board=7.0) <- click here
Whine here if there is some improvement needed concerning usability / interface
You can also write requests to any related subforum. e.g. you want WMP integration with AVIdemux, then you can write it to this Windows subforum.
