I am running the Lightroom 2.0 Public Beta and like what I see so far. I love the dual monitor support and the many many keyboard shortcuts (e.g. '<' and '>' to cycle through basic adjustments in develop, ';' to reset the adjustment, plus/minus to make the adjustments go up and down and command/control f11 to toggle the the second monitor on and off). Haven't tried the localized adjustment too much; initially it's a bit confusing to me because it doesn't have a preview, otherwise the fantastic what's new in Lightroom instructions by Ian Lyons are very helpful. Looking forward to the upcoming Lightroom 2.0 videos from Michael Reichmann . It's non production-quality but I don't see any reason for early adopter enthusiastic amateurs like myself not to try it out.

From Adobe Photoshop Lightroom Public Beta:


As a result of user feedback the engineers have enhanced the Basic adjustment panel so that it's now possible to cycle through the controls using either the comma '< 'or period '>' keys. The keyboard '+/-' keys now increase/decrease the active control, and larger adjustments can be obtained by holding down the 'Shift' key when holding down the '+/-' keys. Tapping the semi-colon ';' key resets the active control to its default value.

The Clarity control can now be adjusted for negative values, which has the effect of softening images. This particular feature is likely to be ore useful when applied as a local correction brush than globally.
