With almost a year since the last stable release, Shareaza has (long since) begun to look stale to users who aren't aware of the hard work being done on the daily alpha-builds.
SkinVista was started for personal-use back in April, but has benefitted from a long summer of fine-tuning, and is probably the most advanced interface yet created for Shareaza. Unfortunately it is only the second skin that I know of this year.
Perhaps something aesthetic like this can hold people over until the developers commit to another wide release.
