wow, who uses the UI anymore, just right click on the files.

Wow!

Who cares what the ui looks like as long as the thing works? Always trips me out when the only thing some one can complain about is the ui. I mean, like how long do you set there and stare at the darn thing anyway? Sheesh!!

I'm fine with the butt ugly UI of the program itself. As you said, right click works fine, but the file icons, arrrgh.

Yeah, I agree with that. The icons aren't the greatest looking ones.

7-zip works wonderfully well so why have they been in perpetual alpha releases for about a year now? Does the team have no confidence in their own code? I've never had it hang, freeze or crash archiving, unzipping or anything of the sort.
