I Totally agree. Forget Icons, if someone wants a colorfull front-end, peazip (peazip.sf.net) is really good, opensource and multiplatform too (and based on 7z binary, don't know on non-windows platform). 7-zip is perfect as is. :-)
BTW: even releasing 9.30 alpha as beta (with sources) would be greatly appreciated. Or publishing the sources in a git/svn/whatever_you_like repository, or the diffs from the latest source release.
So we can make the changes ourselves w/o "tormenting" Mr. Pavlov. I'm mostly curious about the LZMA SDK enhancements, they would have a major impact on some other tools (installers, upx, backup programs and so on).
