Good to know, thanks - I wasn't even aware of the beta.
I keep trying different photo management options for Linux, but have mostly settled on Picasa. I'd prefer something native - Picasa on Linux is still essentially a Windows app, running via Wine. However, its feature set is well beyond the native Linux photo management apps I've seen.
Took a look around, and they're still building Linux/Wine versions - although v3 is still in beta. Here's the download link, for my fellow C-Brat penguins...I'll be checking it out over the next few days.
