Panic has released a 2.0 version of Unison, their Usenet news reader for Mac OS X. I really liked Unison 1.0, enough to write up detailed feature requests for muting sub-threads and such, and got positive responses from Panic, but I never expected they were actually willing to work on a 2.0 release. The new version is definitely gorgeous, with some user interface ideas that are obviously good, and some I'm optimistic will prove themselves. (I can't claim to read Usenet often enough to really push Unison to its limits, and I haven't yet tried to reproduce the inspirations for my years-old feature requests to see if new needs have been met.)

This just blew me away: their list multi-select UI uses a gradient over the span of a set. Love it!
