I love AVS video editor, simple to use and fast. However it does lack decent audio mixing tools, what I'd like to see if new version is better tools to help sync audio file that have recorded on separate device, mp3 recorder or a Zoom H1. At present is pretty hard to sync external audio with that of the video, even using a clapper board it's hard. so here's what I think might help.
The ability to zoom in on the wave form off any audio, that way you can see where the peek (clap from the board) is
Would be cool of you could select the separate audio file and nudge it frame by frame until the 2 audio file match perfectly.
Anyway those addition would make great software - Awesome.
